1. Probably the upper lobe of the liver. Burnt with sacrifice, Ex. 29:13, 22; Lev. 3:4, 10, 15; 4:9; 7:4; 8:16, 25; 9:10, 19.
2. Netted caps, Isa. 3:18.
(Heb. yothe'reth; i.e., "something redundant"), the membrane which covers the upper part of the liver (Ex. 29:13, 22; Lev. 3:4, 10, 15; 4:9; 7:4; marg., "midriff"). In Hos. 13:8 (Heb. seghor; i.e., "an enclosure") the pericardium, or parts about the heart, is meant.
CAUL [smith]a sort of ornamental head-dress, (Isaiah 3:18) with a net for its base. The name is derived from the caul, the membranous bag which encloses the heart--the pericardium. --ED.
CAUL [isbe]CAUL - kol:
(1) yothereth (Ex 29:13), the large lobe or flap of the liver, which is usually mentioned together with the kidneys and the fat as the special portions set aside for the burnt offering (Lev 3:4,10,15; 4:9; 7:4; 8:16,25; 9:10,19).
(2) ceghor (from the root caghar, "to enclose," "shut up"), Hos 13:8, literally the enclosure or covering of the heart, the caul or pericardium, or perhaps the chest as surrounding the heart. It must not be forgotten, however, that the expression may be taken in the sense of "mailcoat of the heart," i.e. hardened heart, which is shut to the influence of God's grace. So Luther and many modern translators and commentators.
