Every thing that opens the womb in all flesh, which they bring unto the LORD, whether it be of men or animals, shall be yours: nevertheless the firstborn of man shall you surely redeem, and the firstling of unclean animals shall you redeem.
Because all the firstborn are mine; for on the day that I struck all the firstborn in the land of Egypt I hallowed unto me all the firstborn in Israel, both man and animal: mine shall they be: I am the LORD.
