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 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.

bol'-ster: Found in the King James Version only in 1 Samuel 19:13, 16, "Behold, the teraphim was in the bed, with the pillow of goat's hair at the head thereof" (the King James Version "for his bolster"), and 1 Samuel 26:7, 11, 12, 16, "Saul lay sleeping. with his spear stuck in the ground at his head." "Bolster" in these passages in the King James Version was used to translate a Hebrew word whose true significance is "the place of the head," or "the head-place." It will be noted that it has disappeared from the Revised Version (British and American), which rightly has throughout "head," instead of "bolster."
