1 Samuel 21:10
And David arose, and fled that day for fear of Saul, and went to Achish the king of Gath.
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 Psalms 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.
