'Joined' in the Bible

Now Jehoshaphat had riches and honour in abundance, and joined affinity with Ahab.

And he joined himself with him to make ships to go to Tarshish: and they made the ships in Eziongeber.

Then Eliezer the son of Dodavah of Mareshah prophesied against Jehoshaphat, saying, Because thou hast joined thyself with Ahaziah, the LORD hath broken thy works. And the ships were broken, that they were not able to go to Tarshish.
