Adam Clarke on Psalms 54:7

For he hath delivered me - Saul had now decamped; and was returned to save his territories; and David in the meanwhile escaped to En-gedi. God was most evidently the author of this deliverance.

Mine eye hath seen his desire upon mine enemies - It is not likely that this Psalm was written after the death of Saul; and therefore David could not say that he had seen his desire. But there is nothing in the text for his desire; and the words might be translated, My eye hath seen my enemies - they have been so near that I could plainly discover them. Thus almost all the Versions have understood the text. I have seen them, and yet they were not permitted to approach me. God has been my Deliverer.
