Achish king of Gath - It appears from the title that Psalm 34 was composed on this occasion. (See the note there.) Nothing can give a more lively impression of the straits to which David was reduced than the fact of his going to the country of the Philistines.

Went to Achish the king of Gath - This was the worst place to which he could have gone: it was the very city of Goliath, whom he had slain, and whose sword he now wore; and he soon found, from the conversation of the servants of Achish, that his life was in the most imminent danger in this place.

And David arose and fled that day for fear of Saul,.... He had fled before for fear of him both from his own house, and from Naioth, 1 Samuel 19:18; but now he fled out of the land of Israel, for fear of him; or it may be the reason of his fear and flight on this day was because of Doeg the Edomite, lest he should go directly to Saul, and tell him where he was; and therefore through fear of him would not stay any longer, but the same day he came, he fled:

and went to Achish the king of Gath; Gath, according to Bunting (p), was twenty four miles from Nob. Achish, the king of it, is called Abimelech in the title of the thirty fourth psalm, see Psalm 34:1, that name being common to the kings of the Philistines, as Pharaoh was to the kings of Egypt. It may seem strange that David should go into an enemy's country, and especially to the country of the Philistines, by whom he was mortally hated for the victories he had obtained over them, and the numbers of them he had slain; and particularly that he should go to Gath, the place of Goliath, their champion, whom he had slain, and whose sword he now had with him: but this is to be said for him, that such was the fury of Saul against him, and his resolution to slay him, that he was as safe in an enemy's country as in the land of Israel; and that if he must die, he might as well die in one place as another; and that he went particularly here, the reason might be, because all other lands were at peace with Saul, and so would have delivered him up to him, had he went elsewhere; but this people were at war with him, and he might hope not to be known by them; and if he was, that they might think it their interest, to detain such a person that was so serviceable to Saul, and so harmful to them; and being Saul's enemy, they might hope to engage him on their side against him; and besides, he might know that Achish was well disposed towards him, as he seems to be, and might like him never the worse for cutting off Goliath's head, who might not be heartily in the interest of Achish. After all, as impolitic as this step of David's may seems to be, it is what great men have taken in their distress, to go over to their enemies, as Themistocles to the Molossians, and Alcibiades to the Lacedemonians.

David with Achish at Gath. - David fled from Nob to Achish of Gath. This Philistian king is called Abimelech in the heading of Psalm 34, according to the standing title of the Philistian princes at Gath. The fact that David fled at once out of the land, and that to the Philistines at Gath, may be accounted for from the great agitation into which he had been thrown by the information he had received from Jonathan concerning Saul's implacable hatred. As some years had passed since the defeat of Goliath, and the conqueror of Goliath was probably not personally known to many of the Philistines, he might hope that he should not be recognised in Gath, and that he might receive a welcome there with his few attendants, as a fugitive who had been driven away by Saul, the leading foe of the Philistines.

(Note: This removes the objection raised by modern critics to the historical credibility of the narrative before us, namely, that David would certainly not have taken refuge at once with the Philistines, but would only have gone to them in the utmost extremity (Thenius). It is impossible to see how the words "he fled that day for fear of Saul" (1 Samuel 21:11) are to prove that this section originally stood in a different connection, and are only arbitrarily inserted here (Thenius). Unless we tear away the words in the most arbitrary manner from the foregoing word ויּברח, they not only appear quite suitable, but even necessary, since David's journey to Abimelech was not a flight, or at all events it is not described as a flight in the text; and David's flight from Saul really began with his departure from Nob. Still less can the legendary origin of this account be inferred from the fact that some years afterwards David really did take refuge with Achish in the Philistian country (1 Samuel 27:1-12 and 1 Samuel 29:1-11), or the conjecture sustained that this is only a distorted legend of that occurrence. For if the later sojourn of David with Achish be a historical fact, that popular legend could not possibly have assumed a form so utterly different as the account before us, to say nothing of the fact that this occurrence has a firm historical support in Psalm 34:1.)

But in this he was mistaken. He was recognised at once by the courtiers of Achish. They said to their prince, "Is not this David the king of the land? Have they not sung in circles, Saul hath slain his thousands, and David his ten thousands?" (cf. 1 Samuel 18:6-7). "King of the land" they call David, not because his anointing and divine election were known to them, but on account of his victorious deeds, which had thrown Saul entirely into the shade. Whether they intended by these words to celebrate David as a hero, or to point him out to their prince as a dangerous man, cannot be gathered from the words themselves, nor can the question be decided with certainty at all (cf. 1 Samuel 29:5).

And David arose, and {h} fled that day for fear of Saul, and went to Achish the king of Gath.

(h) That is, out of Saul's domain.

21:10 To Achish - A strange action; but it must be considered, that Saul's rage was so great, his power also, and diligence in hunting after him that he despaired of escaping any other way: and a desperate disease, produceth a desperate remedy. The king elect is here an exile: anointed to the crown, and yet forced to run his country. So do God's providences sometimes run counter to his promises, for the trial of our faith, and the glorifying his name in accomplishing his counsels, notwithstanding the difficulties that lie in the way.

1Sa 21:10-15. At Gath He Feigns Himself Mad.

10. David . fled . to Achish the king of Gath-which was one of the five principalities of the Philistines. In this place his person must have been known, and to venture into that country, he their greatest enemy, and with the sword of Goliath in his hand, would seem to have been a perilous experiment; but, doubtless, the protection he received implies that he had been directed by the divine oracle. Achish was generous (1Sa 27:6). He might wish to weaken the resources of Saul, and it was common in ancient times for great men to be harbored by neighboring princes.

21:10-15 God's persecuted people have often found better usage from Philistines than from Israelites. David had reason to put confidence in Achish, yet he began to be afraid. His conduct was degrading, and discovered wavering in his faith and courage. The more simply we depend on God, and obey him, the more comfortably and surely we shall walk through this troublesome world.
