'Ruler' in the Bible

The experts in the law who came down from Jerusalem said, "He is possessed by Beelzebul," and, "By the ruler of demons he casts out demons."

But Jesus, paying no attention to what was said, told the synagogue ruler, "Do not be afraid; just believe."

They came to the house of the synagogue ruler where he saw noisy confusion and people weeping and wailing loudly.
