EJ2000(i)
14 Every anathema in Israel shall be thine.
15 Every thing that opens the womb in all flesh, which they shall offer unto the LORD, whether it is of men or animals, shall be thine; nevertheless the firstborn of man shalt thou surely ransom, and the firstborn of unclean animals shalt thou ransom.
16 And from a month old shalt thou effect their ransom, a ransom according to thine estimation, for the price of five shekels, after the shekel of the sanctuary, which is twenty gerahs.
