Charles Ellicott Commentary Psalms 44:4

"Thou art my King, O God: Command deliverance for Jacob." — Psalms 44:4 (ASV)

You are my King. —Literally, You, He, my king, an idiomatic way of making a strong assertion, You, even you, are my king, O God. . What God has done in the past may be expected again, and for a moment the poet forgets the weight of actual trouble in the faith that has sprung from the grateful retrospect over the past.
