1 Then they told David, saying, Behold, the Philistines fight against Keilah, and they rob the threshingfloors.   2 Therefore David enquired of the LORD, saying, Shall I go and smite these Philistines? And the LORD said unto David, Go, and smite the Philistines, and save Keilah.   3 And David's men said unto him, Behold, we be afraid here in Judah: how much more then if we come to Keilah against the armies of the Philistines?   4 Then David enquired of the LORD yet again. And the LORD answered him and said, Arise, go down to Keilah; for I will deliver the Philistines into thine hand.   5 So David and his men went to Keilah, and fought with the Philistines, and brought away their cattle, and smote them with a great slaughter. So David saved the inhabitants of Keilah.   6 And it came to pass, when Abiathar the son of Ahimelech fled to David to Keilah, that he came down with an ephod in his hand.

      Now we find why the prophet Gad (by divine direction, no doubt) ordered David to go into the land of Judah, ch. xxii. 5. It was that, since Saul neglected the public safety, he might take care of it, notwithstanding the ill treatment that was given him; for he must render good for evil, and therein be a type of him who not only ventured his life, but laid down his life, for those that were his enemies.

      I. Tidings are brought to David, as to the patron and protector of his country's liberties, that the Philistines had made a descent upon the city of Keilah and plundered the country thereabouts, v. 1. Probably it was the departure both of God and David from Saul that encouraged the Philistines to make this incursion. When princes begin to persecute God's people and ministers, let them expect no other than vexation on all sides. The way for any country to be quiet is to let God's church be quiet in it. If Saul fight against David, the Philistines shall fight against his country.

      II. David is forward enough to come in for their relief, but is willing to enquire of the Lord concerning it. Here is an instance, 1. Of David's generosity and public-spiritedness. Though his head and hands were full of his own business, and he had enough to do, with the little force he had, to secure himself, yet he was concerned for the safety of his country and could not sit still to see that ravaged: nay, though Saul, whose business it was to guard the borders of his land, hated him and sought his life, yet he was willing, to the utmost of his power, to serve him and his interests against the common enemy, and bravely abhorred the thought of sacrificing the common welfare to his private revenge. Those are unlike to David who sullenly decline to do good because they have not been so well considered as they deserved for the services they have done. 2. Of David's piety and regard to God. He enquired of the Lord by the prophet Gad; for it should seem (by v. 6) that Abiathar came not to him with the ephod till he was in Keilah. His enquiry is, Shall I go and smite these Philistines? He enquires both concerning the duty (whether he might lawfully take Saul's work out of his hand, and act without a commission from him) and concerning the event, whether he might safely venture against such a force as the Philistines had with such a handful of men at his feet, and such a dangerous enemy as Saul was at his back. It is our duty, and will be our case and comfort, whatever happens, to acknowledge God in all our ways and to seek direction from him.

      III. God appointed him once and again to go against the Philistines, and promised him success: Go, and smite the Philistines, v. 2. His men opposed it, v. 3. No sooner did he begin to have soldiers of his own than he found it hard enough to manage them. They objected that they had enemies enough among their own countrymen, they needed not to make the Philistines their enemies. Their hearts failed them when they only apprehended themselves in danger from Saul's band of pursuers, much more when they came to engage the Philistine-armies. To satisfy them, therefore, he enquired of the Lord again, and now received, not only a full commission, which would warrant him to fight though he had no orders from Saul (Arise, go down to Keilah), but also a full assurance of victory: I will deliver the Philistines into thy hand, v. 4. This was enough to animate the greatest coward he had in his regiment.

      IV. He went accordingly against the Philistines, routed them, and rescued Keilah, (v. 5), and it should seem he made a sally into the country of the Philistines, for he carried off their cattle by way of reprisal for the wrong they did to the men of Keilah in robbing their threshing-floors. Here notice is taken (v. 6) that it was while David remained in Keilah, after he had cleared it of the Philistines, that Abiathar came to him with the ephod in his hand, that is, the high priest's ephod, in which the urim and thummim were. It was a great comfort to David, in his banishment, that when he could not go to the house of God he had some of the choicest treasures of that house brought to him, the high priest and his breast-plate of judgment.
