John Calvin Commentary Psalms 97:9

"For thou, Jehovah, art most high above all the earth: Thou art exalted far above all gods." — Psalms 97:9 (ASV)

For you, Jehovah, are high above all the earth. Having already explained these words in another place, I will not say more about them now.

However, it should be noted that a comparison is drawn between God, the angels, and whatever has any claim to eminence. The Psalmist limits all other excellence in such a way as to leave no room for questioning that all majesty is contained in God alone.

This was especially the case when God manifested himself in his only-begotten Son, who is the express image of himself. Before that period, his greatness was less apparent because he was less known.
