14 Every devoted thing among the children of Israel shall be yours.
15 And everything that opens the womb of all flesh, whatsoever they bring to the Lord, whether man or beast, shall be yours: only the firstborn of men shall be surely redeemed, and you shall redeem the firstborn of unclean cattle.
16 And the redemption of them shall be from a month old; their valuation of five shekels — it is twenty gerahs according to the holy shekel.
