Contradiction with Isaiah 57:1
This verse suggests that the righteous are taken away and none understands, implying that the oppressed go unnoticed, whereas Psalms 102:20 claims God hears the groaning of the oppressed.
Isaiah 57:1: The righteous perisheth, and no man layeth [it] to heart: and merciful men [are] taken away, none considering that the righteous is taken away from the evil [to come]. [merciful...: Heb. men of kindness, or, godliness] [from...: or, from that which is evil]
Contradiction with Proverbs 10:3
This verse states that the LORD will not allow the soul of the righteous to famish, while Psalms 102:20 implies God is attentive to the cries due to neglect or affliction.
Proverbs 10:3: The LORD will not suffer the soul of the righteous to famish: but he casteth away the substance of the wicked. [the substance...: or, the wicked for their wickedness]
Contradiction with Psalm 37:25
This verse asserts that the righteous will not be forsaken or beg bread, which seems contrary to Psalms 102:20's implication that the suffering poor need God's intervention.
Psalm 37:25: I have been young, and [now] am old; yet have I not seen the righteous forsaken, nor his seed begging bread.
Contradiction with Ecclesiastes 7:15
This verse observes that sometimes the righteous perish despite righteousness, contradicting Psalms 102:20's implication of divine attention to their afflictions.

Contradiction with Matthew 5:45
Jesus mentions that God makes the sun rise on the evil and the good, contradicting Psalms 102:20's implication that God specifically listens to the cries of the oppressed.
Matthew 5:45: That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.
Contradiction with Job 21:7
This verse questions why the wicked live on and become powerful, seemingly contradicting the notion in Psalms 102:20 that God listens to the groaning of the oppressed, implying imminent support.
