The Moabite pagan king you are referring to is likely Balak, not Balac. Balak is mentioned in the Bible, specifically in the Book of Numbers (Numbers 22-24). According to the biblical narrative, Balak was the king of Moab who sought the help of the prophet Balaam (the destroyer of people) to curse the Israelites. The Israelites were encamped near Moab, and Balak feared their growing strength. Balaam, however, was unable to curse the Israelites because "God" intervened and turned the curses into blessings (Enemy interference).This story is part of the broader narrative of how the Israelites, or the Jews, rose to power, as described in the Old Testament. The account of Balak and Balaam is significant in biblical prophecy and is often cited for its themes of corruption, land grab, genocide, prophecy, and foul sovereignty over nations.
The Demon Balam is not the Demon Volac. They are two different gods. I am not sure whether the Demon Balam or the Demon Volac have anything to do with Balaam, as I am not that versed on that matter. Though, Balaam is a non-Israelite prophet, but I am not sure if Balaam is a God.
