The following is the results of your search for bolster.
Bolster: The Hebrew word kebir, rendered "pillow" in
(1 Samuel 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 Samuel 26:7,11,16) It is rightly rendered in Revised Version "at his
head." In
(Genesis 28:11,18) the Authorized Version renders it "for his
pillows," and the Revised Version "under his head." In
(Ezekiel 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.
