Numbers 18:15-17

15Every thing that openethH6363 the matrixH7358 in all fleshH1320, which they bringH7126 unto YhwhH3068, whether it be of menH120 or beastsH929, shall be thine: nevertheless the firstbornH1060 of manH120 shalt thou surelyH6299 redeemH6299, and the firstlingH1060 of uncleanH2931 beastsH929 shalt thou redeemH6299.

16And those that are to be redeemedH6299 from a monthH2320 oldH1121 shalt thou redeemH6299, according to thine estimationH6187, for the moneyH3701 of fiveH2568 shekelsH8255, after the shekelH8255 of the sanctuaryH6944, which is twentyH6242 gerahsH1626.

17But the firstlingH1060 of a cowH7794, or the firstlingH1060 of a sheepH3775, or the firstlingH1060 of a goatH5795, thou shalt not redeemH6299; they are holyH6944: thou shalt sprinkleH2236 their bloodH1818 upon the altarH4196, and shalt burnH6999 their fatH2459 for an offering made by fireH801, for a sweetH5207 savourH7381 unto YhwhH3068.
