ERV(i)
14 Every thing devoted in Israel shall be thine.
15 Every thing that openeth the womb, of all flesh which they offer unto the LORD, both of man and beast, shall be thine: nevertheless the firstborn of man shalt thou surely redeem, and the firstling of unclean beasts shalt thou redeem.
16 And those that are to be redeemed of them from a month old shalt thou redeem, according to thine estimation, for the money of five shekels, after the shekel of the sanctuary (the same is twenty gerahs).
