"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." (NIV)
But the firstling of a cow or of a sheep or of a goat you shall not redeem. They [as the firstborn of clean beasts belong to God and] are holy. You shall sprinkle their blood upon the altar and shall burn their fat for an offering made by fire, for a sweet and soothing odor to the Lord. (AMP)
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. (KJV)
