Shemot 24:4-6

Orthodox Jewish Bible

⁴ And Moshe wrote kol divrei Hashem, and rose up early in the boker, and built a Mizbe’ach at the base of HaHar, and twelve matzevah (stone pillars), according to the twelve Shivtei Yisroel.

⁵ And he sent out na’arei Bnei Yisroel, which offered olot (burnt offerings), and sacrificed shelamim (peace offerings) of bulls unto Hashem.

⁶ And Moshe took half of the dahm, and put it in bowls; and the other half of the dahm he sprinkled upon the Mizbe’ach.
