Numbers 18:17

But the firstborn of a cow , or the firstborn of a sheep , or the firstborn of a goat , you shall not redeem ; they are holy . You shall sprinkle their blood on the altar and shall burn their fat as a food offering , with a pleasing aroma to the Lord .

“But you must not redeem the firstborn of a cow, a sheep or a goat; they are holy. Splash their blood against the altar and burn their fat as a food offering, an aroma pleasing to the Lord.

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.
