'Alliance' in the Bible

Now Jehoshaphat had riches and honor in abundance, and he made an alliance with Ahab through marriage.

After this, Judah’s King Jehoshaphat made an alliance with Israel’s King Ahaziah, who was guilty of wrongdoing.

Jehoshaphat formed an alliance with him to make ships to go to Tarshish, and they made the ships in Ezion-geber.

Then Eliezer son of Dodavahu of Mareshah prophesied against Jehoshaphat, saying, “Because you formed an alliance with Ahaziah, the Lord has broken up what you have made.” So the ships were wrecked and were not able to go to Tarshish.
