Hadad

Haddad - בעל הדד - حداد (in Ugaritic Haddu) was a very important northwest Semitic storm and rain god, cognate in name and origin with the Akkadian god Adad. Hadad is often called simply Ba‘al Lord, but this title is also used for other gods. Hadad was equated with the Anatolian storm-god Teshub, the Egyptian god Set, the Greek god Zeus, and the Roman god Jupiter.
