God is a Firm Foundation; Man? Not So Much...

Psalm 11: 4 The Lord is in his holy temple;
    the Lord's throne is in heaven;
    his eyes see, his eyelids test the children of man.
5 The Lord tests the righteous,
    but his soul hates the wicked and the one who loves violence.

Psalm 12:5 “Because the poor are plundered, because the needy groan,
    I will now arise,” says the Lord;
    “I will place him in the safety for which he longs.”

In these successive psalms of David, he continues to cling to the righteousness of God (see the end of Psalm 11).  Though everyone around him tells him to "run for the hills," David chooses to look to the Holy Hill of God.  He calls out to Him once again while surrounded by evil men.  He clings to Him as the one who looks down on those who are being wrongly mistreated, who then says "Enough of this: "I AM going to do something."  David clings to the words of God as true, trusting Him to do as He says He will. It is the very character of God that assures us God hears, He cares, and His righteousness will prevail in the end.
