Psalms 44:4

4.Thou, even thou, art my King, O God! In this verse the faithful express still more plainly what I have already alluded to a little before, namely, that the goodness of God was not only apparent in the deliverance of his people, but also flowed upon them in continued succession from age to age; and therefore it is said, Thou, even thou, art my King In my judgment, the demonstrative pronoun הוא, hu, imports as much as if the prophet had put together a long series of the benefits of God after the first deliverance; so that it might appear, that God, who had once been the deliverer of his people, did not show himself otherwise towards their posterity: unless, perhaps, it might be considered as emphatic, and employed for the purpose of asserting the thing stated the more strongly, namely, that the faithful praise God alone as the guardian of their welfare to the exclusion of all others, and the renunciation of aid from any other quarter. Hence they also present the prayer, that God would ordain and send forth new deliverances to his people; for, as he has in his power innumerable means of preservation and deliverance, he is said to appoint and send forth deliverances as his messengers wherever it seems good to him.
