Numbers 18:15-17 all that bursts the matrix of all flesh, which they oblate to Yah Veh - human or animal, becomes yours: only, in redeeming, redeem the firstbirths of humanity and redeem the firstlings of foul animals:

ECB⁽ⁱ⁾ ¹⁵ all that bursts the matrix of all flesh, which they oblate to Yah Veh - human or animal, becomes yours: only, in redeeming, redeem the firstbirths of humanity and redeem the firstlings of foul animals: ¹⁶ and of those to redeem, sons of a month, redeem according to your appraisal, for the silver of five shekels, after the shekel of the holies, which is twenty gerahs. ¹⁷ But the firstling of an ox, or the firstling of a lamb, or the firstling of a goat, redeem not - they are holy: sprinkle their blood on the sacrifice altar and incense their fat for a firing for a scent of rest to Yah Veh.
