1. To the Israelites, Be still, i.e. Do you henceforth silently and quietly wait upon me without fear or diffidence. Or rather, 2. To the heathen, who had raged, Psalms 46:6; and therefore now he seasonably admonisheth them to be still, and to stir no more against God's people. I am God, the only true and almighty God; and your gods are but dumb and impotent idols. I will be exalted, i.e. I will make myself glorious by my great and wonderful works.
