Exodus 12:1-28 1 The Lord said to Moses and Aaron in the land of Egypt, 2 “This month shall be for you the beginning of months. It shall be the first month of the year for you. 3 Tell all the congregation of Israel that on the tenth day of this month every man shall take a lamb according to their fathers' houses, a lamb for a household. 4 And if the household is too small for a lamb, then he and his nearest neighbor shall take according to the number of persons; according to what each can eat you shall make your count for the lamb. 5 Your lamb shall be without blemish, a male a year old. You may take it from the sheep or from the goats, 6 and you shall keep it until the fourteenth day of this month, when the whole assembly of the congregation of Israel shall kill their lambs at twilight. 7 “Then they shall take some of the blood and put it on the two doorposts and the lintel of the houses in which they eat it. 8 They shall eat the flesh that night, roasted on the fire; with unleavened bread and bitter herbs they shall eat it. 9 Do not eat any of it raw or boiled in water, but roasted, its head with its legs and its inner parts. 10 And you shall let none of it remain until the morning; anything that remains until the morning you shall burn. 11 In this manner you shall eat it: with your belt fastened, your sandals on your feet, and your staff in your hand. And you shall eat it in haste. It is the Lord's Passover. 12 For I will pass through the land of Egypt that night, and I will strike all the firstborn in the land of Egypt, both man and beast; and on all the gods of Egypt I will execute judgments: I am the Lord. 13 The blood shall be a sign for you, on the houses where you are. And when I see the blood, I will pass over you, and no plague will befall you to destroy you, when I strike the land of Egypt. 14 “This day shall be for you a memorial day, and you shall keep it as a feast to the Lord; throughout your generations, as a statute forever, you shall keep it as a feast. 15 Seven days you shall eat unleavened bread. On the first day you shall remove leaven out of your houses, for if anyone eats what is leavened, from the first day until the seventh day, that person shall be cut off from Israel. 16 On the first day you shall hold a holy assembly, and on the seventh day a holy assembly. No work shall be done on those days. But what everyone needs to eat, that alone may be prepared by you. 17 And you shall observe the Feast of Unleavened Bread, for on this very day I brought your hosts out of the land of Egypt. Therefore you shall observe this day, throughout your generations, as a statute forever. 18 In the first month, from the fourteenth day of the month at evening, you shall eat unleavened bread until the twenty-first day of the month at evening. 19 For seven days no leaven is to be found in your houses. If anyone eats what is leavened, that person will be cut off from the congregation of Israel, whether he is a sojourner or a native of the land. 20 You shall eat nothing leavened; in all your dwelling places you shall eat unleavened bread.” 21 Then Moses called all the elders of Israel and said to them, “Go and select lambs for yourselves according to your clans, and kill the Passover lamb. 22 Take a bunch of hyssop and dip it in the blood that is in the basin, and touch the lintel and the two doorposts with the blood that is in the basin. None of you shall go out of the door of his house until the morning. 23 For the Lord will pass through to strike the Egyptians, and when he sees the blood on the lintel and on the two doorposts, the Lord will pass over the door and will not allow the destroyer to enter your houses to strike you. 24 You shall observe this rite as a statute for you and for your sons forever. 25 And when you come to the land that the Lord will give you, as he has promised, you shall keep this service. 26 And when your children say to you, ‘What do you mean by this service?’ 27 you shall say, ‘It is the sacrifice of the Lord's Passover, for he passed over the houses of the people of Israel in Egypt, when he struck the Egyptians but spared our houses.’” And the people bowed their heads and worshiped. 28 Then the people of Israel went and did so; as the Lord had commanded Moses and Aaron, so they did.

Exodus 12:43-50 43 And the Lord said to Moses and Aaron, “This is the statute of the Passover: no foreigner shall eat of it, 44 but every slave that is bought for money may eat of it after you have circumcised him. 45 No foreigner or hired worker may eat of it. 46 It shall be eaten in one house; you shall not take any of the flesh outside the house, and you shall not break any of its bones. 47 All the congregation of Israel shall keep it. 48 If a stranger shall sojourn with you and would keep the Passover to the Lord, let all his males be circumcised. Then he may come near and keep it; he shall be as a native of the land. But no uncircumcised person shall eat of it. 49 There shall be one law for the native and for the stranger who sojourns among you.” 50 All the people of Israel did just as the Lord commanded Moses and Aaron. 51 And on that very day the Lord brought the people of Israel out of the land of Egypt by their hosts.

Matthew 21:1-11 1 Now when they drew near to Jerusalem and came to Bethphage, to the Mount of Olives, then Jesus sent two disciples, 2 saying to them, “Go into the village in front of you, and immediately you will find a donkey tied, and a colt with her. Untie them and bring them to me. 3 If anyone says anything to you, you shall say, ‘The Lord needs them,’ and he will send them at once.” 4 This took place to fulfill what was spoken by the prophet, saying, 5 “Say to the daughter of Zion, ‘Behold, your king is coming to you, humble, and mounted on a donkey, on a colt, the foal of a beast of burden.’” 6 The disciples went and did as Jesus had directed them. 7 They brought the donkey and the colt and put on them their cloaks, and he sat on them. 8 Most of the crowd spread their cloaks on the road, and others cut branches from the trees and spread them on the road. 9 And the crowds that went before him and that followed him were shouting, “Hosanna to the Son of David! Blessed is he who comes in the name of the Lord! Hosanna in the highest!” 10 And when he entered Jerusalem, the whole city was stirred up, saying, “Who is this?” 11 And the crowds said, “This is the prophet Jesus, from Nazareth of Galilee.”

Mark 11:1-11 1 Now when they drew near to Jerusalem, to Bethphage and Bethany, at the Mount of Olives, Jesus sent two of his disciples 2 and said to them, “Go into the village in front of you, and immediately as you enter it you will find a colt tied, on which no one has ever sat. Untie it and bring it. 3 If anyone says to you, ‘Why are you doing this?’ say, ‘The Lord has need of it and will send it back here immediately.’” 4 And they went away and found a colt tied at a door outside in the street, and they untied it. 5 And some of those standing there said to them, “What are you doing, untying the colt?” 6 And they told them what Jesus had said, and they let them go. 7 And they brought the colt to Jesus and threw their cloaks on it, and he sat on it. 8 And many spread their cloaks on the road, and others spread leafy branches that they had cut from the fields. 9 And those who went before and those who followed were shouting, “Hosanna! Blessed is he who comes in the name of the Lord! 10 Blessed is the coming kingdom of our father David! Hosanna in the highest!” 11 And he entered Jerusalem and went into the temple. And when he had looked around at everything, as it was already late, he went out to Bethany with the twelve.

Luke 19:28-40 28 And when he had said these things, he went on ahead, going up to Jerusalem. 29 When he drew near to Bethphage and Bethany, at the mount that is called Olivet, he sent two of the disciples, 30 saying, “Go into the village in front of you, where on entering you will find a colt tied, on which no one has ever yet sat. Untie it and bring it here. 31 If anyone asks you, ‘Why are you untying it?’ you shall say this: ‘The Lord has need of it.’” 32 So those who were sent went away and found it just as he had told them. 33 And as they were untying the colt, its owners said to them, “Why are you untying the colt?” 34 And they said, “The Lord has need of it.” 35 And they brought it to Jesus, and throwing their cloaks on the colt, they set Jesus on it. 36 And as he rode along, they spread their cloaks on the road. 37 As he was drawing near—already on the way down the Mount of Olives—the whole multitude of his disciples began to rejoice and praise God with a loud voice for all the mighty works that they had seen, 38 saying, “Blessed is the King who comes in the name of the Lord! Peace in heaven and glory in the highest!” 39 And some of the Pharisees in the crowd said to him, “Teacher, rebuke your disciples.” 40 He answered, “I tell you, if these were silent, the very stones would cry out.”

John 12:12-19 12 The next day the large crowd that had come to the feast heard that Jesus was coming to Jerusalem. 13 So they took branches of palm trees and went out to meet him, crying out, “Hosanna! Blessed is he who comes in the name of the Lord, even the King of Israel!” 14 And Jesus found a young donkey and sat on it, just as it is written, 15 “Fear not, daughter of Zion; behold, your king is coming, sitting on a donkey’s colt!” 16 His disciples did not understand these things at first, but when Jesus was glorified, then they remembered that these things had been written about him and had been done to him. 17 The crowd that had been with him when he called Lazarus out of the tomb and raised him from the dead continued to bear witness. 18 The reason why the crowd went to meet him was that they heard he had done this sign. 19 So the Pharisees said to one another, “You see that you are gaining nothing. Look, the world has gone after him.”

Esther 9:20-32 20 And Mordecai recorded these things and sent letters to all the Jews who were in all the provinces of King Ahasuerus, both near and far, 21 obliging them to keep the fourteenth day of the month Adar and also the fifteenth day of the same, year by year, 22 as the days on which the Jews got relief from their enemies, and as the month that had been turned for them from sorrow into gladness and from mourning into a holiday; that they should make them days of feasting and gladness, days for sending gifts of food to one another and gifts to the poor. 23 So the Jews accepted what they had started to do, and what Mordecai had written to them. 24 For Haman the Agagite, the son of Hammedatha, the enemy of all the Jews, had plotted against the Jews to destroy them, and had cast Pur (that is, cast lots), to crush and to destroy them. 25 But when it came before the king, he gave orders in writing that his evil plan that he had devised against the Jews should return on his own head, and that he and his sons should be hanged on the gallows. 26 Therefore they called these days Purim, after the term Pur. Therefore, because of all that was written in this letter, and of what they had faced in this matter, and of what had happened to them, 27 the Jews firmly obligated themselves and their offspring and all who joined them, that without fail they would keep these two days according to what was written and at the time appointed every year, 28 that these days should be remembered and kept throughout every generation, in every clan, province, and city, and that these days of Purim should never fall into disuse among the Jews, nor should the commemoration of these days cease among their descendants. 29 Then Queen Esther, the daughter of Abihail, and Mordecai the Jew gave full written authority, confirming this second letter about Purim. 30 Letters were sent to all the Jews, to the 127 provinces of the kingdom of Ahasuerus, in words of peace and truth, 31 that these days of Purim should be observed at their appointed seasons, as Mordecai the Jew and Queen Esther obligated them, and as they had obligated themselves and their offspring, with regard to their fasts and their lamenting. 32 The command of Esther confirmed these practices of Purim, and it was recorded in writing.

Job 1:1-5 1 There was a man in the land of Uz whose name was Job, and that man was blameless and upright, one who feared God and turned away from evil. 2 There were born to him seven sons and three daughters. 3 He possessed 7,000 sheep, 3,000 camels, 500 yoke of oxen, and 500 female donkeys, and very many servants, so that this man was the greatest of all the people of the east. 4 His sons used to go and hold a feast in the house of each one on his day, and they would send and invite their three sisters to eat and drink with them. 5 And when the days of the feast had run their course, Job would send and consecrate them, and he would rise early in the morning and offer burnt offerings according to the number of them all. For Job said, “It may be that my children have sinned, and cursed God in their hearts.” Thus Job did continually.
