Psalms 118:11

They compassed me about; yea, they compassed me about,.... Which is repeated not only for the confirmation of, it, but to denote the frequency and fury of their attacks, and their obstinate persisting therein; [See comments on Psalms 118:10];

but in the name of the Lord I will destroy them; which also is repeated to show the strength of his faith, and the continuance of it, notwithstanding his numerous enemies, and their violent efforts against him.
