But the firstling of a cow, or the firstling of a sheep, or the firstling of a goat, thou shalt not redeem; they [are] holy: thou shalt sprinkle their blood upon the altar, and shalt burn their fat [for] an offering made by fire, for a sweet savour unto the LORD.
Berean Study Bible (BSB) - Numbers 18:17 >But you must not redeem the firstborn of an ox, a sheep, or a goat; they are holy. You are to sprinkle their blood on the altar and burn their fat as an offering made by fire, a pleasing aroma to the LORD.
