Leaf: of a tree. The olive-leaf mentioned Genesis 8:11. The barren fig-tree had nothing but leaves (Matthew 21:19; Mark 11:13). The oak-leaf is mentioned Isaiah 1:30; 6:13. There are numerous allusions to leaves, their flourishing, their decay, and their restoration (Leviticus 26:36; Isaiah 34:4; Jeremiah 8:13; Daniel 4:12,14,21; Mark 11:13; 13:28). The fresh leaf is a symbol of prosperity (Psalm 1:3; Jeremiah 17:8; Ezekiel 47:12); the faded, of decay (Job 13:25; Isaiah 1:30; 64:6; Jeremiah 8:13).
