Jamieson, Fausset and Brown on 2 Chronicles 20:35-37

35-37. after this did Jehoshaphat ... join himself with Ahaziah ... to make ships--A combined fleet was built at Ezion-geber, the destination of which was to voyage to Tartessus, but it was wrecked. Jehoshaphat's motive for entering into this partnership was to secure a free passage through Israel, for the vessels were to be conveyed across the Isthmus of Suez, and to sail to the west of Europe from one of the ports of Palestine on the Mediterranean. Eliezer, a prophet, denounced this unholy alliance, and foretold, as divine judgment, the total wreck of the whole fleet. The consequence was, that although Jehoshaphat broke off--in obedience to the divine will--his league with Ahaziah, he formed a new scheme of a merchant fleet, and Ahaziah wished to be admitted a partner [1Ki 22:48]. The proposal of the Israelitish king was respectfully declined [1Ki 22:49]. The destination of this new fleet was to Ophir, because the Israelitish seaports were not accessible to him for the Tartessus trade; but the ships, when just off the docks, were wrecked in the rocky creek of Ezion-geber.
