Spears » Stuck in the ground beside the bolster during sleep
So David and Abishai came to the people by night: and, behold, Saul lay sleeping within the place of the wagons, with his spear stuck in the ground at his head; and Abner and the people lay around him. Then Abishai said to David, "God has delivered up your enemy into your hand this day. Now therefore please let me strike him with the spear to the earth at one stroke, and I will not strike him the second time." David said to Abishai, "Don't destroy him; for who can put forth his hand against Yahweh's anointed, and be guiltless?" read more.
David said, "As Yahweh lives, Yahweh will strike him; or his day shall come to die; or he shall go down into battle and perish. Yahweh forbid that I should put forth my hand against Yahweh's anointed; but now please take the spear that is at his head, and the jar of water, and let us go."
