He hath made his people - utterly to abhor him - This deception, which Dr. Delaney says "did harm to nobody, and to the account of which he is at an utter loss what degree of guilt to charge," imposed upon Achish, had the most direct tendency to make him imagine himself secure, while in the utmost danger; and to have a faithful friend and able ally in David, while he was the veriest enemy he could possibly have. Shame on him who becomes the apologist of such conduct! As to Dr. Chandler, he should know that no lie is of the truth, and that all falsity is an abomination to the Lord.

And Achish believed David,.... As he would have him understand his story; imposing upon him by ambiguous terms, insinuating he had been against the southern parts of Judah, when he had been against foreign nations that lay to the south of Judah:

saying, he hath made his people Israel utterly to abhor him; they shall never forgive him the destruction of their cities, and the inhabitants of them, and the plunder of their goods and cattle; his name will be had in the utmost detestation and abhorrence, and he must never return thither any more:

therefore he shall be my servant for ever: would be glad to continue with him as a servant, and be obliged to serve him faithfully and truly, since his own people, and even those of his own tribe, would never more receive him; it being, as he understood it, the south of Judah that he had been plundering.

1 Samuel 27:12 is connected with 1 Samuel 27:10; Achish believed David's words, and said (to himself), "He hath made himself stinking (i.e., hated) among his own people, among Israel, and will be my servant (i.e., subject to me) for ever."

And Achish believed David, saying, He hath made his people Israel utterly to abhor him; therefore he shall be my servant for ever.

utterly...: Heb. to stink

27:8-12 While David was in the land of the Philistines, he attacked some remains of the devoted nations. The people whom he cut off were long before doomed to destruction. It is often wisdom to shun public notice, but we must in no situation be idle. We must always try to do somewhat in the cause of God. This expedition David hid from Achish. But an equivocation which serves the purpose of a lie, is as like to it as a hypocrite is to a profane person, it is only better in appearance, therefore more dangerous. Yet, though believers often manifest imperfections, they can never be prevailed upon to renounce the service of God, and to unite interests with his enemies, or finally to become the servants of sin and Satan. But what a train of evils follow from unbelief! When we forget the Lord's past mercies, and his gracious assurances, we shall be overwhelmed with desponding fears, and probably be led to adopt some dishonourable method to get rid of our troubles. Nothing can so effectually establish us in holy tempers and practices, and preserve us from perplexities, as firm, unshaken dependence upon the promises of God in Christ Jesus.
