Liver

The large and heavy gland that secretes the bile. In the sacrifices it is named only to point out the caul which is above it (Ex. 29:13,2213And thou shalt take all the fat that covereth the inwards, and the caul that is above the liver, and the two kidneys, and the fat that is upon them, and burn them upon the altar. (Exodus 29:13)
22Also thou shalt take of the ram the fat and the rump, and the fat that covereth the inwards, and the caul above the liver, and the two kidneys, and the fat that is upon them, and the right shoulder; for it is a ram of consecration: (Exodus 29:22); Lev. 3:44And 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. (Leviticus 3:4)). To be wounded in the liver is fatal (Pro. 7:2323Till a dart strike through his liver; as a bird hasteth to the snare, and knoweth not that it is for his life. (Proverbs 7:23)). The liver being poured out is symbolical of deep anguish (Lam. 2:1111Mine eyes do fail with tears, my bowels are troubled, my liver is poured upon the earth, for the destruction of the daughter of my people; because the children and the sucklings swoon in the streets of the city. (Lamentations 2:11), compare Job 16:1313His archers compass me round about, he cleaveth my reins asunder, and doth not spare; he poureth out my gall upon the ground. (Job 16:13)). Among the heathen the liver was one of the parts of an animal that were examined in order to foretell events, as practiced by the king of Babylon (Ezek. 21:2121For the king of Babylon stood at the parting of the way, at the head of the two ways, to use divination: he made his arrows bright, he consulted with images, he looked in the liver. (Ezekiel 21:21)).
