Adam Clarke on Psalms 57:11

Be thou exalted, O God, above the heavens - The same sentiments and words which occur in Psa 57:5 (note). See the note there.

David was not only in a happy state of mind when he wrote this Psalm, but in what is called a state of triumph. His confidence in God was unbounded; though encompassed by the most ferocious enemies, and having all things against him except God and his innocence. David will seldom be found in a more blessed state than he here describes. Similar faith in God will bring the same blessings to every true Christian in similar circumstances.
