The Most Holy Body and Blood of Christ (Corpus Christi), Year B: 1st Reading

Exodus 24:3-8

When Moses came to the people
   and related all the words and ordinances of the LORD,
   they all answered with one voice,
   “We will do everything that the LORD has told us.”
Moses then wrote down all the words of the LORD and,
   rising early the next day,
   he erected at the foot of the mountain an altar
   and twelve pillars for the twelve tribes of Israel.
Then, having sent certain young men of the Israelites
   to offer holocausts and sacrifice young bulls
   as peace offerings to the LORD,
   Moses took half of the blood and put it in large bowls;
   the other half he splashed on the altar.
Taking the book of the covenant, he read it aloud to the people,
   who answered, “All that the LORD has said, we will heed and do.”
Then he took the blood and sprinkled it on the people, saying,
   “This is the blood of the covenant
   that the LORD has made with you
   in accordance with all these words of his.”
