And the LORD spake unto Moses, saying,
And it came to pass the selfsame day, that the LORD did bring the children of Israel out of the land of Egypt by their hosts.
that thou shalt set apart unto the LORD all that openeth the womb, and every firstling which thou hast that cometh of a beast; the males shall be the LORD'S.
Sanctify unto me all the firstborn, whatsoever openeth the womb among the children of Israel, both of man and of beast: it is mine.
