I will cry unto God most High. In the original, "unto Elohim 'elyon"—an expression which only occurs here and in Psalms 78:56. El elyon, however, occurs in Psalms 78:45; as in Genesis 14:18, Genesis 14:19, Genesis 14:22, and Jehovah 'elyon in Ps 7:18.
Unto God that performeth all things for me (comp. Psalms 138:8). God "accomplishes" for his saints whatever is good for them.
