As jews have stolen everything from their neighboring languages, they also stole the word "Baal" which means "Master" or "Lord". It was originally used for Beelzebul. It is a generic word. Baal-Zebul is another God, namely Zeus. Of course, people also called him Baal before, but jews perverted meanings later to appropriate anything they could and stole many words from their surrounding populations to form their language.
Baal, god worshipped in many ancient Middle Eastern communities, especially among the Canaanites, who apparently considered him a fertility deity and one of the most important gods in the pantheon. Learn more about Baal and the communities that worshipped him in this article.

In the formative stages of
Israel’s history, the presence of Baal names did not necessarily mean
apostasy or even syncretism. The judge
Gideon was also named Jerubbaal (Judges 6:32), and
King Saul had a son named
Ishbaal (I Chronicles 8:33). For those early Hebrews, “Baal” designated the Lord of Israel, just as “Baal” farther north designated the Lord of
Lebanon or of Ugarit. What made the very name Baal
anathema to the Israelites was the program of
Jezebel, in the 9th century bce, to introduce into
Israel her Phoenician cult of Baal in opposition to the official worship of
Yahweh (I Kings 18). By the time of the prophet Hosea (mid-8th century bce) the antagonism to Baalism was so strong that the use of the term Baal was often replaced by the
contemptuous boshet (“shame”); in
compound proper names, for example, Ishbosheth replaced the earlier Ishbaal.
