'Fat' in the Bible

Only the firstborn of an ox or the firstborn of a sheep or the firstborn of a goat you will not redeem; they [are] holy. Their blood you will sprinkle over the altar, and their fat you will turn into smoke [as] an offering made by fire, a fragrance of appeasement for Yahweh.

From all your gifts {you will present} every contribution of Yahweh, from all its fat, the part [that is] sacred.'

You will say to them, 'When {you are presenting} its fat, the rest will be credited to the Levites like a yield of the threshing floor and like a yield from the press.

You will not bear any sin because {you have presented} its fat; you will not defile the holy objects of the {Israelites}, or you will die.'"
