Psalms 34:4

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," 1 Samuel 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, Psalm 34:1 (note).

I sought the Lord, and he heard me - That is, on the occasion referred to in the psalm, when he was exposed to the persecutions of Saul, and when he sought refuge in the country of Abimelech or Achish: 1 Samuel 21:1-15. The idea is, that at that time he did not confide in his own wisdom, or trust to any devices of his own, but that he sought the protection and guidance of God, alike when he fled to Gath, and when he fled from Gath.

And delivered me from all my fears - From all that he apprehended from Saul, and again from all that he dreaded when he found that Abimelech would not harbor him, but drove him from him.
