At the 9/11 10th anniversary ceremony at ground zero, President Obama read a passage from Psalm 46, which reads in part:

Come behold the works of the Lord
who has made desolations in the Earth.
He makes wars cease
to the ends of the Earth.

He breaks the bough
and cuts the spear in two.
He burns the chariot in fire.
Be still and know that I am God.
I will be exalted among the nations.
I will be exalted in the Earths.
