2 Samuel 22:44

Thou also hast delivered me from the strivings of my people, from the insurrections in the midst of his own nation; Thou Hast kept me to be head of the heathen, of all the surrounding nations; a people which I knew not shall serve me, Here the Messianic thought is included, that eventually even those outside 3f the chosen people of the Lord would learn to know the true God in Christ Jesus.
