V.1-4 If the words of Ahab, king of the 10 tribes, were bad in chapter 20:4 (with a Gentile), these words (in verse 4) of the king of Judah to Ahab are worse!
V.5-8 Jehoshaphat, in a wrong association, has a troubled conscience. Ahab is satisfied with the advice of those who told him what he wanted to hear. But there is another faithful man whose advice is not wanted.
V.9-12 Can 400 men be anything but right? Is it true that “in numbers there is strength”? These were the reasonings of the mind, but not God’s thoughts.
V.13-18 Is the truth of God ever “evil” (v. 18)? To the person unwilling to follow God, it is.
