In Isaiah 38:2, the same prayer of Hezekiah is recorded — a parallel account of this event.

In Isaiah 38:3, Hezekiah's prayer is detailed — he pleads his faithfulness, adding depth to the simple prayer mentioned here.

James 5:16 teaches that a righteous person's prayer is powerful, exemplified by Hezekiah's prayer which brought healing.
