A Psalm of praise. Of David
I will exalt you, my God the King;
[You are MY God, I belong to you personally, intimately, continually, completely. And you are THE King, ruler of the universe and beyond, the highest Authority, the final Judge, the righteous Decider of right and wrong.]
I will praise your name for ever and ever.
[This is both because you are worthy and because with you, we will live forever and ever in the eternal life you have provided. What a powerful, positive, wonderful provision of certain hope, purpose and meaning. You are worthy of all worship, all obedience, all praise.]
