Hastings' Dictionary of the Bible (1898)
LEAF. Isa 64:6. The bright fresh color of the leaf of a tree or plant shows that it is richly nourished by a good soil. Hence the fresh leaf is often used in Scripture as a symbol of prosperity, Ps 1:3; Jer 17:8; Eze 47:12; the faded leaf as a symbol of decay. Job 13:25; Isa 1:30; Isa 64:6; Jer 8:13; Eze 17:9. Also other illustrations are derived from leaves. Lev 26:36; Isa 34:4; Dan 4:12, 2 Kgs 22:14, 2 Chr 11:21; Mark 13:28; Rev 22:2.
