This psalm has to of my "go-to" verses-1, and the first part of 10. (In a literal translation, it's "Desist, and know that I am God" Desist! Stop doing whatever it is that you think is going to fix your problem and let the Creator take over.
1God is our refuge and strength, a very present help in trouble.

3Though the waters thereof roar and be troubled, though the mountains shake with the swelling thereof. Selah.
4There is a river, the streams whereof shall make glad the city of God, the holy place of the tabernacles of the most High.
5God is in the midst of her; she shall not be moved: God shall help her, and that right early.

7The LORD of hosts is with us; the God of Jacob is our refuge. Selah.
8Come, behold the works of the LORD, what desolations he hath made in the earth.
9He maketh wars to cease unto the end of the earth; he breaketh the bow, and cutteth the spear in sunder; he burneth the chariot in the fire.
10Be still, and know that I am God: I will be exalted among the heathen, I will be exalted in the earth.
11The LORD of hosts is with us; the God of Jacob is our refuge. Selah.
