31 Jehoshaphat reigned over Judah: he was thirty-five years old when he began to reign; and he reigned twenty-five years in Jerusalem: and his mother’s name was Azubah the daughter of Shilhi. 32 He walked in the way of Asa his father, and didn’t turn aside from it, doing that which was right in the eyes of Yahweh. 33 However the high places were not taken away; neither as yet had the people set their hearts to the God of their fathers. 34 Now the rest of the acts of Jehoshaphat, first and last, behold, they are written in the history of Jehu the son of Hanani, which is inserted in the book of the kings of Israel. 35 After this did Jehoshaphat king of Judah join himself with Ahaziah king of Israel; the same did very wickedly: 36 and he joined himself with him to make ships to go to Tarshish; and they made the ships in Ezion Geber. 37 Then Eliezer the son of Dodavahu of Mareshah prophesied against Jehoshaphat, saying, Because you have joined yourself with Ahaziah, Yahweh has destroyed your works. The ships were broken, so that they were not able to go to Tarshish.

Commentary on 2 Chronicles 20:31-37
(Read 2 Chronicles 20:31-37)
Jehoshaphat kept close to the worship of God, and did what he could to keep his people close to it. But after God had done such great things for him, given him not only victory, but wealth; after this, to go and join himself with a wicked king, was very ungrateful. What could he expect but that God would be angry with him? Yet it seems, he took the warning; for when Ahaziah afterward pressed him to join him, he would not, 1 Kings 22:49. Thus the alliance was broken, and the Divine rebuke had its effect, at least for a season. Let us be thankful for any losses which may have prevented the loss of our immortal souls. Let us praise the Lord, who sought after us, and left us not to perish in our sins.
