5 Then David rose and came to the place where Saul had encamped; and David saw the place where Saul lay, with Abner the 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 Ahim'elech the Hittite, and to Jo'ab's brother Abi'shai the son of Zeru'iah, "Who will go down with me into the camp to Saul?" And Abi'shai said, "I will go down with you." 7 So David and Abi'shai went to the army by night; and there lay Saul sleeping within the encampment, with his spear stuck in the ground at his head; and Abner and the army lay around him. 8 Then said Abi'shai to David, "God has given your enemy into your hand this day; now therefore let me pin him to the earth with one stroke of the spear, and I will not strike him twice." 9 But David said to Abi'shai, "Do not destroy him; for who can put forth his hand against the Lord'S anointed, and be guiltless?" 10 And David said, "As the Lord lives, the Lord will smite him; or his day shall come to die; or he shall go down into battle and perish. 11 The Lord forbid that I should put forth my hand against the Lord'S anointed; but take now the spear that is at his head, and the jar of water, and let us go." 12 So David took the spear and the jar of water from Saul's head; and they went away. No man saw it, or knew it, nor did any awake; for they were all asleep, because a deep sleep from the Lord had fallen upon them.

13 Then David went over to the other side, and stood afar off on the top of the mountain, with a great space between them; 14 and David called to the army, and to Abner the son of Ner, saying, "Will you not answer, Abner?" Then Abner answered, "Who are you that calls to the king?"

Matthew Henry's Commentary on 1 Samuel 26:5-14

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.

Commentary on 1 Samuel 26:13-20

(Read 1 Samuel 26:13-20)

David reasoned seriously and affectionately with Saul. Those who forbid our attendance on God's ordinances, do what they can to estrange us from God, and to make us heathens. We are to reckon that which exposes us to sin the greatest injury that can be done us. If the Lord stirred thee up against me, either in displeasure to me, taking this way to punish me for my sins against him, or in displeasure to thee, if it be the effect of that evil spirit from the Lord which troubles thee; let Him accept an offering from us both. Let us join in seeking peace, and to be reconciled with God by sacrifice.
