New Defender's Study Bible Notes
18:5 He trusted in the LORD God of Israel. Hezekiah was arguably the most godly of all the kings of Judah, yet his father Ahaz was probably the most ungodly. Perhaps the testimony of his grandfather, Jotham, or his great grandfather, Uzziah, influenced him toward Jehovah. More likely, he was pointed to the Lord by the prophet Isaiah, who was a frequent spokesman for God at the king’s court.
