1. Samuel 29:6

Thou hast been upright - So he thought, for as yet he had not heard of the above transaction; David having given him to understand that he had been fighting against Israel.

DAVID MARCHING WITH THE PHILISTINES TO FIGHT WITH ISRAEL. (Sa1 29:1-5) Aphek-- (Jos 12:8), in the tribe of Issachar, and in the plain of Esdraelon. A person who compares the Bible account of Saul's last battle with the Philistines, with the region around Gilboa, has the same sort of evidence that the account relates what is true, that a person would have that such a battle as Waterloo really took place. Gilboa, Jezreel, Shunem, En-dor, are all found, still bearing the same names. They lie within sight of each other. Aphek is the only one of the cluster not yet identified. Jezreel on the northern slope of Gilboa, and at the distance of twenty minutes to the east, is a large fountain, and a smaller one still nearer; just the position which a chieftain would select, both on account of its elevation and the supply of water needed for his troops [HACKETT, Scripture Illustrated].

Then Achish called David,.... Being so near him, that he could call unto him himself, or he sent some person to him, to require his presence with him: and said unto him, surely, as the Lord liveth; or "Jehovah liveth"; an oath by the true God, of whom Achish might have some knowledge, as he also had of angels, from his conversation with David; though the Heathens had a notion of a supreme Being, and yet worshipped other gods, and whom they called Jove, from this name of Jehovah. Kimchi observes, that all confess a first cause; and therefore when he swore to David, he swore by him in whom David believed, perhaps out of complaisance to him, or that David might pay the greater regard to his oath: thou hast been upright; sincere, honest, faithful, and just in all his deportment; yet not so sincere as he thought him to be, witness the road he pretended he had taken against the south of Judah, Sa1 27:1, and thy going out and thy coming in with me in the host is good in sight; his behaviour in the army, attending him as the keeper of his head, or captain of his bodyguard, was exceeding agreeable to him, and he could wish to have him continued: for I have not found evil in thee, since the day of thy coming unto me unto this day; whatever he had done before to the Philistines, having greatly afflicted and distressed them in his wars with them, of which this seems to be an exception: nevertheless, the lords favour thee not; or thou art not acceptable to them, yea, very offensive and disagreeable.

After this declaration on the part of the princes, Achish was obliged to send David back. Sa1 29:6-7 With a solemn assertion, - swearing by Jehovah to convince David all the more thoroughly of the sincerity of his declaration, - Achish said to him, "Thou art honourable, and good in my eyes (i.e., quite right in my estimation) are thy going out and coming in (i.e., all thy conduct) with me in the camp, for I have not found anything bad in thee; but in the eyes of the princes thou art not good (i.e., the princes do not think thee honourable, do not trust thee). Turn now, and go in peace, that thou mayest do nothing displeasing to the princes of the Philistines." Sa1 29:8-9 Partly for the sake of vindicating himself against this suspicion, and partly to put the sincerity of Achish's words to the test, David replied, "What have I done, and what hast thou found in thy servant, since I was with thee till this day, that I am not to come and fight against the enemies of my lord the king?" These last words are also ambiguous, since the king whom David calls his lord might be understood as meaning either Achish or Saul. Achish, in his goodness of heart, applies them without suspicion to himself; for he assures David still more earnestly (Sa1 29:9), that he is firmly convinced of his uprightness. "I know that thou art good in my eyes as an angel of God," i.e., I have the strongest conviction that thou hast behaved as well towards me as an angel could; but the princes have desired thy removal. Sa1 29:10 "And now get up early in the morning with the servants of thy lord (i.e., Saul, whose subjects David's men all were), who have come with thee; get ye up in the morning when it gets light for you (so that ye can see), and go." Sa1 29:11 In accordance with this admonition, David retur…

If the reasons Achish had to trust David were stronger than the reasons which the princes offered why they should distrust him (as I do not see that, in policy, they were, for the princes were certainly in the right), yet Achish was but one of five, though the chief, and the only one that had the title of king; accordingly, in a council of war held on this occasion, he was over-voted, and obliged to dismiss David, though he was extremely fond of him. Kings cannot always do as they would, nor have such as they would about them. I. The discharge Achish gives him is very honourable, and not a final discharge, but only from the present service. 1. He signifies the great pleasure and satisfaction he had taken in him and in his conversation: Thou art good in my sight as an angel of God, Sa1 29:9. Wise and good men will gain respect, wherever they go, from all that know how to make a right estimate of persons and things, though of different professions in religion. What Achish says of David, God, by the prophet, says of the house of David (Zac 12:8), that it shall be as the angel of the Lord. But the former is a court-compliment; the latter is a divine promise. 2. He gives him a testimonial of his good behaviour, Sa1 29:6. It is very full and in obliging terms: "Thou hast been upright, and thy whole conduct has been good in my sight, and I have not found evil in thee." Saul would not have given him such a testimonial, though he had done far more service to him than Achish. God's people should behave themselves always so inoffensively as if possible to get the good word of all they have dealings with; and it is a debt we owe to those who have acquitted themselves well to give them the praise of it. 3. He lays all the blame of his dismission upon the princes, who would by no mea…

29:6 by the Lord: Achish used the unique name of Israel’s God to prove his own sincerity. • a trustworthy ally: This assertion was not completely true, though Achish did not realize it (27:8-12).
