Psalm 73

Note: "An upright person, disconcerted by the prosperity of the wicked decides to stay true to God."

28. "But for me it is good to be near God; I have made the Lord God my refuge, that I may tell of all thy works."

This one was written by Asaph. From Wikipedia:

He was the grandson of the Israelite prophet Samuel (1 Chronicles 6:24). He and his male descendants were set aside by King David to worship God in song and music (1 Chronicles 15:16-17). He authored Psalms 50, and Psalms 73 to 83.
