From Webster's Revised Unabridged Dictionary (1913) [web1913]:
   Leaf \Leaf\, n.; pl. {Leaves}. [OE. leef, lef, leaf, AS.
      le[a0]f; akin to S. l[?]f, OFries. laf, D. loof foliage, G.
      laub,OHG. loub leaf, foliage, Icel. lauf, Sw. l[94]f, Dan.
      l[94]v, Goth. laufs; cf. Lith. lapas. Cf. {Lodge}.]
      1. (Bot.) A colored, usually green, expansion growing from
            the side of a stem or rootstock, in which the sap for the
            use of the plant is elaborated under the influence of
            light; one of the parts of a plant which collectively
            constitute its foliage.
  
      Note: Such leaves usually consist of a blade, or lamina,
               supported upon a leafstalk or petiole, which, continued
               through the blade as the midrib, gives off woody ribs
               and veins that support the cellular texture. The
               petiole has usually some sort of an appendage on each
               side of its base, which is called the stipule. The
               green parenchyma of the leaf is covered with a thin
               epiderm pierced with closable microscopic openings,
               known as stomata.
  
      2. (Bot.) A special organ of vegetation in the form of a
            lateral outgrowth from the stem, whether appearing as a
            part of the foliage, or as a cotyledon, a scale, a bract,
            a spine, or a tendril.
  
      Note: In this view every part of a plant, except the root and
               the stem, is either a leaf, or is composed of leaves
               more or less modified and transformed.
  
      3. Something which is like a leaf in being wide and thin and

                  upon its opposite sides.
            (b) A side, division, or part, that slides or is hinged,
                  as of window shutters, folding doors, etc.
            (c) The movable side of a table.
            (d) A very thin plate; as, gold leaf.

From Easton's 1897 Bible Dictionary [easton]:
   Leaf
      of a tree. The olive-leaf mentioned Gen. 8:11. The barren

      oak-leaf is mentioned Isa. 1:30; 6:13. There are numerous
      allusions to leaves, their flourishing, their decay, and their

      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).
