'Alliance' in the Bible

Jehoshaphat was very wealthy and greatly respected. He made an alliance by marriage with Ahab,

Later King Jehoshaphat of Judah made an alliance with King Ahaziah of Israel, who did evil.

Eliezer son of Dodavahu from Mareshah prophesied against Jehoshaphat, "Because you made an alliance with Ahaziah, the Lord will shatter what you have made." The ships were wrecked and unable to go to sea.
