Leaf

of a tree. The olive-leaf mentioned Gen. 8:11. The barren
fig-tree had nothing but leaves (Matt. 21:19; Mark 11:13). The
oak-leaf is mentioned Isa. 1:30; 6:13. There are numerous
allusions to leaves, their flourishing, their decay, and their
restoration (Lev. 26:36; Isa. 34:4; Jer. 8:13; Dan. 4:12, 14,
21; Mark 11:13; 13:28). The fresh leaf is a symbol of prosperity
(Ps. 1:3; Jer. 17:8; Ezek. 47:12); the faded, of decay (Job
13:25; Isa. 1:30; 64:6; Jer. 8:13).

Leaf of a door (1 Kings 6:34), the valve of a folding door.

Leaf of a book (Jer. 36:23), perhaps a fold of a roll.
