Be still, and know that I am God: I will be exalted among the heathen, I will be exalted in the earth.
Be still, and know that I am God. His miraculous interposition for His people proved that Yahweh (H3068) of Israel is 'Elohiym (H430) - i:e., God. The transition is most impressive, the covenant people the speaking triumphantly of God among themselves (Psalms 46:1-7), then calling on the pagan to behold His works (Psalms 46:8-9), and now God Himself commanding the pagan troublers of His people, "He still," - i:e., Desist from your mad attempt to fight against Omnipotence arrayed on the side of God's people. This word He shall at last speak, not merely as a counsel, but as a command, carrying with it the effect, the ungodly being forever rendered incapable of disturbing the kingdom of God.
I will be exalted among the pagan. Yahweh's words here correspond to Hezekiah's prayer (Isaiah 37:20). Compare introduction. The result in Hezekiah's time accordingly was (2 Chronicles 32:23) "Many brought gifts unto the Lord to Jerusalem, and presents to Hezekiah king of Judah; so that he was magnified in the sight of all nations from thenceforth." An earnest of the more world-wide result of God's visible interposition for His people in the last days.
