LXX2012(i)
14 Every devoted thing among the children of Israel shall be your.
15 And every thing that opens the womb of all flesh, whatever they bring to the Lord, whether man or beast, shall be your: 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 oboli according to the holy shekel.
