Everything that opens the womb of all flesh, which they bring to the Lord, whether it is of men or animals, will be yours. However, you will surely redeem the firstborn of man, and the firstborn of unclean beasts you will redeem.
because all the firstborn are Mine, for on the day that I struck all the firstborn in the land of Egypt I set apart to Me all the firstborn in Israel, both man and beast. They shall be Mine. I am the Lord.
