In Job 15:10, Eliphaz counters the rhetorical question about being first man by citing the elders' presence — directly rebutting Job's implied claim.

In Job 12:12, Job himself said wisdom is with the aged — Eliphaz's question turns Job's own earlier point against him, highlighting his inconsistency.

In Job 38:4-41, God asks Job the same kind of question about being present at creation — the cross-reference shows God later echoes Eliphaz's irony.

In Job 38:21, God sarcastically says Job knows because he was born then — mirroring Eliphaz's 'first man' taunt.

Proverbs 8:25 says Wisdom was brought forth before the hills — contrasting Eliphaz's mockery that Job wasn't.

In Psalm 90:2, God alone exists before the mountains — contrasting Job's finitude with God's eternity, deepening the irony of Eliphaz's question.

In Proverbs 8:22-25, wisdom claims to be brought forth before the hills — a direct contrast to Job; only wisdom has that pre-existence, not man.
