“Kidneys” From Concise Bible Dictionary:

Bovine Kidneys
These, “with the fat thereof,” were often burned on the altar in the sacrifices (Lev. 3:4-154And the two kidneys, and the fat that is on them, which is by the flanks, and the caul above the liver, with the kidneys, it shall he take away. 5And Aaron's sons shall burn it on the altar upon the burnt sacrifice, which is upon the wood that is on the fire: it is an offering made by fire, of a sweet savor unto the Lord. 6And if his offering for a sacrifice of peace offering unto the Lord be of the flock; male or female, he shall offer it without blemish. 7If he offer a lamb for his offering, then shall he offer it before the Lord. 8And he shall lay his hand upon the head of his offering, and kill it before the tabernacle of the congregation: and Aaron's sons shall sprinkle the blood thereof round about upon the altar. 9And he shall offer of the sacrifice of the peace offering an offering made by fire unto the Lord; the fat thereof, and the whole rump, it shall he take off hard by the backbone; and the fat that covereth the inwards, and all the fat that is upon the inwards, 10And the two kidneys, and the fat that is upon them, which is by the flanks, and the caul above the liver, with the kidneys, it shall he take away. 11And the priest shall burn it upon the altar: it is the food of the offering made by fire unto the Lord. 12And if his offering be a goat, then he shall offer it before the Lord. 13And he shall lay his hand upon the head of it, and kill it before the tabernacle of the congregation: and the sons of Aaron shall sprinkle the blood thereof upon the altar round about. 14And he shall offer thereof his offering, even an offering made by fire unto the Lord; the fat that covereth the inwards, and all the fat that is upon the inwards, 15And the two kidneys, and the fat that is upon them, which is by the flanks, and the caul above the liver, with the kidneys, it shall he take away. (Leviticus 3:4‑15); Lev. 4:99And the two kidneys, and the fat that is upon them, which is by the flanks, and the caul above the liver, with the kidneys, it shall he take away, (Leviticus 4:9); Lev. 7:44And the two kidneys, and the fat that is on them, which is by the flanks, and the caul that is above the liver, with the kidneys, it shall he take away: (Leviticus 7:4), and more.
