Concise Bible Dictionary:

1. Son of Bedad and king of Edom (Gen. 36:35-36; 1 Chron. 1:46-47).
2. An Edomite of the royal family. When a child he was carried into Egypt: Pharaoh eventually gave him his sister-in-law as wife. On the death of David he returned to his own country, and, being stirred up by God, was an enemy and did mischief to Solomon (1 Kings 11:14-22).
3. Son of Ishmael (1 Chron. 1:30). Called HADAR in Genesis 25:15.
4. King of Edom who succeeded Baal-hanan (1 Chron. 1:50-51). Called HADAR in Genesis 36:39. Apparently “Hadad” was a title of the kings of Edom rather than a name.
