Verse 4
I sought the Lord - This is the reason and cause of his gratitude. I sought the Lord, and he heard me, and delivered me out of all my fears. This answers to the history; for when David heard what the servants of Achish said concerning him, "he laid up the words in his heart, and was greatly afraid," 1Sam 21:13. To save him, God caused the epileptic fit to seize him; and, in consequence, he was dismissed by Achish, as one whose defection from his master, and union with the Philistines, could be of no use, and thus David's life and honor were preserved. The reader will see that I proceed on the ground laid down by the Septuagint. See before, Psa 34:1 (note).
