Sanctify unto me all the firstborn, whatsoever opens the womb among the children of Israel, both of man and of beast: it is mine.

That you shall set apart unto the LORD all that opens the womb, and every firstling that comes of a beast which you have; the males shall be the LORD'S.

And it came to pass, when Pharaoh refused to let us go, that the LORD slew all the firstborn in the land of Egypt, both the firstborn of man, and the firstborn of beast: therefore I sacrifice to the LORD all that opens the womb, being males; but all the firstborn of my children I redeem.

All that opens the womb is mine; and every firstling among your cattle, whether ox or sheep, that is male.
