Jehoram was the son of King Jehoshaphat, and he ruled in the southern kingdom of Judah from 853 to 841 BC. The other King Jehoram was the son of the wicked King Ahab, and he ruled in the northern kingdom of Israel from 852 to 841 BC . The name Joram is a shortened form of Jehoram. Complicating matters is the fact that both Jehorams were brothers-in-law to each other.
