Job 11:3 has Zophar accusing Job of mocking — while Job 13:9 turns the mockery accusation back on the friends; opposite direction of blame.

Psalm 44:21 affirms that God knows hidden secrets of the heart, directly paralleling Job's rhetorical question about deceiving God in 13:9. Both assert God's omniscience.

Psalm 139:23 invites God to search and test the heart, mirroring the examination theme in Job 13:9. Both recognize God's ability to scrutinize deeply.

Jeremiah 17:10 declares that the Lord searches the heart and mind, directly corresponding to Job's point that God examines people. A clear parallel on divine scrutiny.

In Galatians 6:7, Paul reinforces that God cannot be mocked — echoing Job's warning that pretending to deceive God is futile.

Matthew 27:41 shows religious leaders mocking Jesus — a concrete NT instance of humans mocking God, fulfilling the pattern Job condemned.
