John Gill

As for me, I will call upon God,.... Not upon a creature, on idols and images, on angels or saints departed; but upon God, in his time of trouble, for salvation and deliverance from enemies; who is able to save. This is to be understood of calling upon God in prayer; as Psa 55:17 explains it, and the Targum here renders it; though sometimes invocation of the name of God takes in the whole of divine worship; and the Lord shall save me; which confidence was founded partly upon his promise to deliver such that call upon him in the day of trouble, Psa 50:15; and partly upon his power, whose hand is not shortened that it cannot save. The Targum is, "the Word of the Lord shall redeem me.''
