Exodus 12:1-8, 11-14
1The 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. 3Tell all the congregation of Israel that on the tenth day of this month they shall take every man a lamb according to their fathers' houses, a lamb for a household; 4and if the household is too small for a lamb, then a man and his neighbor next to his house shall take according to the number of persons; according to what each can eat you shall make your count for the lamb. 5Your lamb shall be without blemish, a male a year old; you shall take it from the sheep or from the goats; 6and you shall keep it until the fourteenth day of this month, when the whole assembly of the congregation of Israel shall kill their lambs in the evening. 7Then they shall take some of the blood, and put it on the two doorposts and the lintel of the houses in which they eat them. 8They shall eat the flesh that night, roasted; with unleavened bread and bitter herbs they shall eat it. 11In this manner you shall eat it: your loins girded, your sandals on your feet, and your staff in your hand; and you shall eat it in haste. It is the LORD's passover. 12For I will pass through the land of Egypt that night, and I will smite all the first-born in the land of Egypt, both man and beast; and on all the gods of Egypt I will execute judgments: I am the LORD. 13The blood shall be a sign for you, upon the houses where you are; and when I see the blood, I will pass over you, and no plague shall fall upon you to destroy you, when I smite 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 you shall observe it as an ordinance for ever.
Psalms 116:12-13, 15-18
12What shall I render to the LORD for all his bounty to me? 13I will lift up the cup of salvation and call on the name of the LORD, 15Precious in the sight of the LORD is the death of his saints. 16O LORD, I am thy servant; I am thy servant, the son of thy handmaid. Thou hast loosed my bonds. 17I will offer to thee the sacrifice of thanksgiving and call on the name of the LORD. 18I will pay my vows to the LORD in the presence of all his people,
1 Corinthians 11:23-26
23For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, 24and when he had given thanks, he broke it, and said, "This is my body which is for you. Do this in remembrance of me." 25In the same way also the cup, after supper, saying, "This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me." 26For as often as you eat this bread and drink the cup, you proclaim the Lord's death until he comes.
1Now before the feast of the Passover, when Jesus knew that his hour had come to depart out of this world to the Father, having loved his own who were in the world, he loved them to the end. 2And during supper, when the devil had already put it into the heart of Judas Iscariot, Simon's son, to betray him, 3Jesus, knowing that the Father had given all things into his hands, and that he had come from God and was going to God, 4rose from supper, laid aside his garments, and girded himself with a towel. 5Then he poured water into a basin, and began to wash the disciples' feet, and to wipe them with the towel with which he was girded. 6He came to Simon Peter; and Peter said to him, "Lord, do you wash my feet?" 7Jesus answered him, "What I am doing you do not know now, but afterward you will understand." 8Peter said to him, "You shall never wash my feet." Jesus answered him, "If I do not wash you, you have no part in me." 9Simon Peter said to him, "Lord, not my feet only but also my hands and my head!" 10Jesus said to him, "He who has bathed does not need to wash, except for his feet, but he is clean all over; and you are clean, but not every one of you." 11For he knew who was to betray him; that was why he said, "You are not all clean." 12When he had washed their feet, and taken his garments, and resumed his place, he said to them, "Do you know what I have done to you? 13You call me Teacher and Lord; and you are right, for so I am. 14If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another's feet. 15For I have given you an example, that you also should do as I have done to you.
