2 Chronicles 32:24-26 adds that Hezekiah became proud after his healing, then humbled himself, averting God's wrath — a detail not in Kings.

Isaiah 38:1-20 records Hezekiah's prayer, the sign of the shadow, and his psalm of thanksgiving — a fuller parallel account of the same illness.

In Jeremiah 18:7-10, God explains that announced judgment can be revoked if people repent — the same principle at work when Hezekiah's death sentence is reversed after his prayer.

In Jonah 3:4-10, Nineveh's repentance leads God to relent from threatened disaster — mirroring Hezekiah's death sentence being revoked after his prayer.

In Deuteronomy 18:22, a prophecy that fails to come true proves a false prophet — but Hezekiah's case shows that conditional prophecies of judgment can be revoked upon repentance, so the test applies only to unconditional predictions.
