Numbers 18:17 DBY

¹⁵  Everything that breaketh open the womb of all flesh, which they present to Jehovah, of men or of beasts, shall be thine; nevertheless the firstborn of man shalt thou in any case ransom, and the firstborn of unclean beasts shalt thou ransom.

¹⁶  And those that are to be ransomed from a month old shalt thou ransom, according to thy valuation, for the money of five shekels, after the shekel of the sanctuary, which is twenty gerahs.

¹⁷  But the firstborn of a cow, or the firstborn of a sheep, or the firstborn of a goat, thou shalt not ransom: they are holy. Thou shalt sprinkle their blood on the altar, and their fat shalt thou burn as an offering by fire for a sweet odour to Jehovah.

¹⁸  And their flesh shall be thine; as the wave-breast and as the right shoulder shall it be thine.

¹⁹  All the heave-offerings of the holy things, which the children of Israel offer to Jehovah, have I given thee, and to thy sons and to thy daughters with thee, by an everlasting statute: it shall be an everlasting covenant of salt before Jehovah unto thee and thy seed with thee.
