How to Understand This
The composer of Psalm 73 struggled with the age-old problem of the suffering of the innocent and the prosperity of the wicked, and he wrote the psalm after coming to a place of resolution (v. 1). The connections between this psalm and Proverbs and Job (see Comment section) indicate that the psalm is a wisdom poem.
Psalm 72 strikes a high note. It is flush with the hopes and dreams for the future. In contrast, Psalm 73 opens Book Three on a note of confusion and doubt. Life with God will not be lived in an idyllic world, at least for the moment, but in a world where the values espoused in the previous psalm do not always meet with the realities of life

In the end the reverse is true; the wicked are slipping (vv. 18–20) and the psalmist is stable (vv. 21–28)”; likewise, initially the wicked seem to be doing well “forever” whereas the psalmist is perpetually afflicted, but in the end the wicked come to a complete end in a moment, whereas actually God was continually with the psalmist and was the psalmist’s allocation “forever.”68 The psalm brings out a feature that characterizes many psalms. The change that comes over the psalmist issued not from Yhwh’s having acted but from the psalmist having gained a conviction that Yhwh will act
