Numbers [In the desert] 18:12-18

¹²“I have given to you all the best of the oil, and all the best of the vintage, and of the grain, the first fruits of them which they give to Adonai .

¹³The first-ripe fruits of all that is in their land, which they bring to Adonai , shall be yours. Everyone who is clean in your house shall eat of it.

¹⁴“Everything devoted in Israel God prevails shall be yours.

¹⁵Everything that opens the womb, of all flesh which they offer to Adonai , both of man and animal shall be yours. Nevertheless, you shall surely redeem the firstborn of man, and you shall redeem the firstborn of unclean animals.

¹⁶You shall redeem those who are to be redeemed of them from a month old, according to your estimation, for five shekels 2 oz; 56.7 g of money, after the shekel of the sanctuary, (the shekel is 0.4oz; 11.34 g; or called twenty gerahs 20/50 of an oz)

¹⁷“But you shall not redeem the firstborn of a cow, or the firstborn of a sheep, or the firstborn of a goat. They are holy. You shall sprinkle their blood on the altar, and shall burn their fat for an offering made by fire, for a pleasant aroma to Adonai .

¹⁸Their meat shall be yours, as the wave offering breast and as the right thigh, it shall be yours.
