David was Ahaz's ancestor. He is the benchmark for judging the spiritual character of Judah's kings (2 Kings 14:3; 1 Kings 15:3, 11).
he walked in the ways of the kings of Israel: Ahaz was one of Judah's most wicked kings. He adopted Israel's false religion and the pagan practices of other nations, even sacrificing his own son in fire (see Jeremiah 19:5; 32:35). Levitical laws forbade such sacrifices as detestable to the Lord (Leviticus 18:10; 20:1–5), yet God's people continued the practice (Isaiah 30:33; Jeremiah 7:31) until Josiah's reforms (2 Kings 23:10).
