Everything that opens the womb in all flesh, which they bring to Jehovah, of men or animals, shall be yours. Nevertheless, the first-born of man you shall surely redeem, and the first-born of unclean animals you shall redeem.
Because all the first-born are Mine. On the day that I struck all the first-born in the land of Egypt I set apart to Myself all the first-born in Israel, both man and animal. They shall be Mine. I am Jehovah.
