Psalms 10:15

"Break thou the arm of the wicked;

And as for the evil man, seek out his wickedness till thou find none.

Jehovah is King forever and ever:

The nations are perished out of his land."

In the days when the sword was the principal weapon of violence, breaking the arm of the wicked would be equivalent to putting him completely out of business.

"The nations are perished out of his land." The event here mentioned is the displacement and extermination that God ordered for the ancient Canaanites in order to replace them with the Chosen People, following their Egyptian slavery and the Wilderness wanderings. Human history effectively demonstrates that any nation which allows its wickedness to come to full flower will ultimately experience the judgment of God against them. Just look at the list of examples: Egypt, Assyria, Babylon, Persia, Greece, Roman, the Muslims, France, Germany, etc., etc.

"Till thou find none." This is not an indication that God shall get all the wickedness out of evil men, but that evil men themselves shall perish utterly. "The thought is not that the wicked devices of ungodly men are not discernible to the Almighty, but that he will so completely have disposed of them that no trace of them will be left."[14] There appears in these verses a promise of God's absolute and final conquest of evil.

"This ultimate triumph of truth and righteousness over all evil is to be surely looked for. Jehovah's universal kingship has been an element of the creed of God's people ever since the call and redemption of Israel (Exodus 15:18). Yes, God's absolute and eternal kingship will in time be realized, even in all the universality and endless duration of it, as foretold in Zechariah 14:9; Daniel 7:14; and Revelation 11:15.[15]
