Exodus 24:4-6

Douay-Rheims 1899 American Edition

⁴ And Moses wrote all the words of the Lord: and rising in the morning he built an altar at the foot of the mount, and twelve titles according to the twelve tribes of Israel.

⁵ And he sent young men of the children of Israel, and they offered holocausts, and sacrificed pacific victims of calves to the Lord.

⁶ Then Moses took half of the blood, and put it into bowls: and the rest he poured upon the altar.
