1-samuel 21:10

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.

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.

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.
