Refuge in God

Psalm 7:1-17
David prayed to the Lord to save and deliver him from all who pursue him.
If I have done this and there is guilt on my hands - let my enemy pursue and overtake me.
Let the Lord judge the peoples. Judge me, O Lord, according to my righteousness, according to my integrity, O Most High. O righteous God, who searches minds and hearts, bring to an end the violence of the wicked and make the righteous secure.
David sang this song because of Cush the Benjamite (this may have been the Ethiopian who told David of the death of Absalom).
The psalmist casts himself on God, knowing his cause is just.
He calls on God to clear his name, to support the right and break the wicked. He describes the terrible fate awaiting those who refuse to repent and closes on a note of thanksgiving.
Why?
God is righteousness so pray to the Lord to judge me and judge those wicked one.
Righteousness: Obey the words and decrees of the Lord.
Integrity: honesty, wholeness;  the quality of being unimpaired未受損傷.
God search our minds and hearts, no one can escape from his eyes.
So the Lord sake for the sake of David ....
How?
God is my refuge, humble myself before the Lord! Give thanks to the Lord.
