'Fat' in the Bible

and what the land is, whether it is fat or lean, whether there is wood therein, or not. Be courageous, and bring of the fruit of the land. Now the time was the time of the first-ripe grapes."

"But you shall not redeem the firstborn of a cow, or the firstborn of a sheep, or the firstborn of a goat. They are holy. You shall sprinkle their blood on the altar, and shall burn their fat for an offering made by fire, for a pleasant aroma to Yahweh.
