Psalms 34:4 - Coke's Commentary on the Holy Bible

And delivered me from all my fears— This exactly answers to the history; which informs us, that when David heard what the servants of Achish said to their master concerning him, He laid up those words in his heart, and was greatly afraid, 1 Samuel 21:13. Undoubtedly, he thought himself in extreme danger; but, instead of removing their suspicions, and his own fears, by offering to join with the Philistines against his country, he rather chose to counterfeit madness, and trust Providence with the success of it, than secure his safety by base and dishonourable compliances.
