3Moses came and told the people all the words of the LORD and all the ordinances; and all the people answered with one voice, and said, "All the words which the LORD has spoken we will do." 4And Moses wrote all the words of the LORD. And he rose early in the morning, and built an altar at the foot of the mountain, and twelve pillars, according to the twelve tribes of Israel. 5And he sent young men of the people of Israel, who offered burnt offerings and sacrificed peace offerings of oxen to the LORD. 6And Moses took half of the blood and put it in basins, and half of the blood he threw against the altar. 7Then he took the book of the covenant, and read it in the hearing of the people; and they said, "All that the LORD has spoken we will do, and we will be obedient." 8And Moses took the blood and threw it upon the people, and said, "Behold the blood of the covenant which the LORD has made with you in accordance with all these words."
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,
11But when Christ appeared as a high priest of the good things that have come, then through the greater and more perfect tent (not made with hands, that is, not of this creation) 12he entered once for all into the Holy Place, taking not the blood of goats and calves but his own blood, thus securing an eternal redemption. 13For if the sprinkling of defiled persons with the blood of goats and bulls and with the ashes of a heifer sanctifies for the purification of the flesh, 14how much more shall the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify your conscience from dead works to serve the living God. 15Therefore he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred which redeems them from the transgressions under the first covenant.
Mark 14:12-16, 22-26
12And on the first day of Unleavened Bread, when they sacrificed the passover lamb, his disciples said to him, "Where will you have us go and prepare for you to eat the passover?" 13And he sent two of his disciples, and said to them, "Go into the city, and a man carrying a jar of water will meet you; follow him, 14and wherever he enters, say to the householder, `The Teacher says, Where is my guest room, where I am to eat the passover with my disciples?' 15And he will show you a large upper room furnished and ready; there prepare for us." 16And the disciples set out and went to the city, and found it as he had told them; and they prepared the passover. 22And as they were eating, he took bread, and blessed, and broke it, and gave it to them, and said, "Take; this is my body." 23And he took a cup, and when he had given thanks he gave it to them, and they all drank of it. 24And he said to them, "This is my blood of the covenant, which is poured out for many. 25Truly, I say to you, I shall not drink again of the fruit of the vine until that day when I drink it new in the kingdom of God." 26And when they had sung a hymn, they went out to the Mount of Olives.
