[14] Every thing devoted in Israel shall be thine. [15] Every thing that openeth the matrix in all flesh, which they bring unto the LORD, whether it be of men or beasts, shall be thine: nevertheless the firstborn of man shalt thou surely and the firstling of unclean beasts shalt thou redeem. [16] And those that are to be redeemed from a month old shalt thou redeem, according to thine estimation, for the money of five shekels, of the sanctuary, which is twenty gerahs.
