The psalm begins by affirming: God is our refuge and strength, a very present help in trouble. Therefore we will not fear though the earth gives way, though the mountains be moved into the heart of the sea, though its waters roar and foam and the mountains tremble at its swelling. The poet uses extreme images of creation's chaos to say that even that does not take away the security of the one who trusts God.
The second part changes the picture: there is a river whose streams make glad the city of God, the holy habitation of the Most High. God is in the midst of her; she shall not be moved; God will help her when morning dawns. The nations rage, the kingdoms totter, but he utters his voice and the earth melts. The refrain declares: the Lord of hosts is with us; the God of Jacob is our fortress.
The third part is an invitation: come, behold the works of the Lord, who has brought desolations on the earth. He makes wars cease to the end of the earth; he breaks the bow, shatters the spear and burns the chariots with fire. Then God speaks: be still, and know that I am God; I will be exalted among the nations, I will be exalted in the earth. The psalm ends by repeating the refrain.
