Webster(i)
14 Every thing devoted in Israel shall be thine.
15 Every thing that openeth the matrix in all flesh, which they bring to the LORD, whether of men or beast, shall be thine: nevertheless, the first born of man shalt thou surely redeem, 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 thy estimation, for the money of five shekels, after the shekel of the sanctuary, which is twenty gerahs.
