Exodus 13:2 “Set apart to me all the firstborn, whatever opens the womb among the sons of Israel, both of man and of animal. It is mine.” Moses said to the people “…It shall be, when Yahweh brings you into the land of the Canaanite, as he swore to you and to your fathers, and will give it you, 12 that you shall cross over to Yahweh all that opens the womb, and every firstborn that comes from an animal which you have. The males shall be Yahweh’s.”
