John Gill Commentary 2 Chronicles 20:37

"Then Eliezer the son of Dodavahu of Mareshah prophesied against Jehoshaphat, saying, Because thou hast joined thyself with Ahaziah, Jehovah hath destroyed thy works. And the ships were broken, so that they were not able to go to Tarshish." — 2 Chronicles 20:37 (ASV)

Then Eliezer the son of Dodavah of Mareshah A city in the tribe of Judah, (Joshua 15:44)

prophesied against Jehoshaphat, saying, because you have joined yourself with Ahaziah; an idolatrous prince, with whom he ought to have had no fellowship, even in civil things, it being both a countenancing him, and exposing himself and people to danger:

the Lord has broken your works; the ships built at the joint expense of the two kings, that is, the Lord had determined to break them, and now foretold that he would; the Targum is, "the Word of the Lord has destroyed your works:" and the ships were broken, that they were not able to go to Tarshish; (See Gill on 1 Kings 22:48).
