⁴ And Moses wrote all the words of the LORD, and rose up early, and set up an altar under the mountain, and twelve pillars, according to the twelve tribes of Israel.

⁵ And he sent young men of the children of Israel, who offered burnt offerings of oxen, and sacrificed peace offerings to the LORD.

⁶ Then, Moses took half of the blood and put it in basins; and he sprinkled half of the blood on the altar.
