David Spares Saul at Ziph

261 Then the Ziphites came to Saul at Gibeah, saying, "David is in hiding on the hill of Hachilah, which is opposite Jeshimon." 2 So Saul rose and went down to the Wilderness of Ziph, with three thousand chosen men of Israel, to seek David in the Wilderness of Ziph. 3 Saul encamped on the hill of Hachilah, which is opposite Jeshimon beside the road. But David remained in the wilderness. When he learned that Saul had come after him into the wilderness, 4 David sent out spies, and learned that Saul had indeed arrived. 5 Then David set out and came to the place where Saul had encamped; and David saw the place where Saul lay, with Abner son of Ner, the commander of his army. Saul was lying within the encampment, while the army was encamped around him.

6 Then David said to Ahimelech the Hittite, and to Joab's brother Abishai son of Zeruiah, "Who will go down with me into the camp to Saul?" Abishai said, "I will go down with you." 7 So David and Abishai went to the army by night; there Saul lay sleeping within the encampment, with his spear stuck in the ground at his head; and Abner and the army lay around him. 8 Abishai said to David, "God has given your enemy into your hand today; now therefore let me pin him to the ground with one stroke of the spear; I will not strike him twice." 9 But David said to Abishai, "Do not destroy him; for who can raise his hand against the Lord's anointed, and be guiltless?" 10 David said, "As the Lord lives, the Lord will strike him down; or his day will come to die; or he will go down into battle and perish. 11 The Lord forbid that I should raise my hand against the Lord's anointed; but now take the spear that is at his head, and the water jar, and let us go." 12 So David took the spear that was at Saul's head and the water jar, and they went away. No one saw it, or knew it, nor did anyone awake; for they were all asleep, because a deep sleep from the Lord had fallen upon them.

Commentary on 1 Samuel 26:1-12

(Read 1 Samuel 26:1-12)

How soon do unholy hearts lose the good impressions convictions have made upon them! How helpless were Saul and all his men! All as though disarmed and chained, yet nothing is done to them; they are only asleep. How easily can God weaken the strongest, befool the wisest, and baffle the most watchful! David still resolved to wait till God thought fit to avenge him on Saul. He will by no means force his way to the promised crown by any wrong methods. The temptation was very strong; but if he yielded, he would sin against God, therefore he resisted the temptation, and trusted God with the event.
