Contradiction with Proverbs 10:16
While Psalms 73:17 suggests understanding comes from God's sanctuary, Proverbs 10:16 asserts that the outcome of life is based on righteousness versus wickedness, not divine insight.
Proverbs 10:16: The labour of the righteous [tendeth] to life: the fruit of the wicked to sin.
Contradiction with Ecclesiastes 8:14
Psalms 73:17 implies justice for the wicked, whereas Ecclesiastes 8:14 laments the perceived lack of justice in life outcomes.
Ecclesiastes 8:14: There is a vanity which is done upon the earth; that there be just [men], unto whom it happeneth according to the work of the wicked; again, there be wicked [men], to whom it happeneth according to the work of the righteous: I said that this also [is] vanity.

Job 21:7: Wherefore do the wicked live, become old, yea, are mighty in power?

Contradiction with Habakkuk 1:13

Habakkuk 1:13: [Thou art] of purer eyes than to behold evil, and canst not look on iniquity: wherefore lookest thou upon them that deal treacherously, [and] holdest thy tongue when the wicked devoureth [the man that is] more righteous than he? [iniquity: or, grievance]
