Charles Ellicott Commentary Psalms 145:1

"I will extol thee, my God, O King; And I will bless thy name for ever and ever." — Psalms 145:1 (ASV)

The psalm opens with familiar psalm strains (compare the openings of Psalm 30 and Psalm 34).

For ever and ever. — In contemplation of the greatness and majesty of God time ceases to be. The poet vows a homage indefinitely prolonged.
