2 Kings 20:3 - Ellicott's Commentary On The Whole Bible

Remember now how I have walked ... — Hezekiah deprecates an untimely death — the punishment of the wicked (Proverbs 10:27) — on account of his zeal for Jehovah and against the idols. As Thenius remarks, there is nothing surprising in his apparent self-praise if we remember such passages as Psalms 18:20; Psalms 7:8; Nehemiah 13:14. Josephus sets down the poignancy of his sorrow to childlessness, and makes him pray to be spared until he get a son; but this is merely an instance of that “midrashitic” enlargement of the narrative which we find elsewhere in that historian.
