And the LORD spoke unto Moses, saying,
And it came to pass the very same day, that the LORD did bring the children of Israel out of the land of Egypt by their hosts.
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.
Sanctify unto me all the firstborn, whatsoever opens the womb among the children of Israel, both of man and of beast: it is mine.
