In Job 6:9, Job wishes God would crush him — a desire for the very persecution he here accuses God of.

In Job 7:20, Job earlier asks why God has made him a target — the same sense of divine persecution echoed here.

In Job 10:14-17, Job describes God hunting him like a lion and bringing fresh troops — the same imagery of divine persecution as here.

In Job 13:25-28, Job says God pursues him like a driven leaf and puts his feet in stocks — echoing the divine cruelty here.

In Job 16:9-14, Job depicts God as a warrior tearing him apart — the same violent persecution described here.

In Job 19:6-9, Job says God has closed his net and walled up his way — the same sense of being trapped and persecuted.

In Job 23:6, Job hoped God would not use His power against him—now in 30:21, that hope is shattered as God attacks ruthlessly.

In Job 13:24, Job asks why God treats him as an enemy—now in 30:21, that treatment is described as a ruthless attack.

Job 33:10 quotes Job's own accusation that God considers him an enemy—the same sentiment behind the ruthless attack in 30:21.

Job 40:2 is God's direct challenge to Job's complaint—the very accusation of ruthless attack that God now demands an answer for.

In Jeremiah 30:14, God speaks of striking Israel as a cruel foe — the same word 'cruel' but in a context of just punishment, contrasting with Job's complaint.

In Psalm 77:7-9, the psalmist questions if God has forgotten to be gracious — a parallel lament of divine withdrawal, though less accusatory.

Psalm 89:13 praises God's mighty hand—the same hand Job experiences as cruel and oppressive in his complaint.

1 Peter 5:6 urges humility under God's mighty hand—Job instead laments that same hand attacking him ruthlessly.
