 bolster
      n : a pillow that is often put across a bed underneath the
          regular pillows [syn: long pillow]
      v 1: support and strengthen; "bolster morale" [syn: bolster up]
      2: prop up with a pillow or bolster
      3: add padding to; "pad the seat of the chair" [syn: pad]


 Bolster
    The Hebrew word _kebir_, rendered "pillow" in 1 Sam. 19:13, 16,
    but in Revised Version marg. "quilt" or "network," probably
    means some counterpane or veil intended to protect the head of
    the sleeper. A different Hebrew word (meraashoth') is used for
    "bolster" (1 Sam. 26:7, 11, 16). It is rightly rendered in
    Revised Version "at his head." In Gen. 28:11, 18 the Authorized
    Version renders it "for his pillows," and the Revised Version
    "under his head." In Ezek. 13:18, 20 another Hebrew word
    (kesathoth) is used, properly denoting "cushions" or "pillows,"
    as so rendered both in the Authorized and the Revised Version.
