Psalm 73:1-3, 16-17

73 Truly God is good to Israel, to those who are pure in heart. 2 

But as for me, my feet had almost stumbled, my steps had nearly slipped. 3 For I was envious of the arrogant when I saw the prosperity of the wicked.

16 But when I thought how to understand this, it seemed to me a wearisome task, 17 until I went into the sanctuary of God; then I discerned their end.
