'Ruler' in the Bible

And the scribes who had come down from Jerusalem were saying, "He is possessed by Beelzebul!" and "By the ruler of the demons he expels the demons!"

But Jesus, ignoring {what was said}, told the ruler of the synagogue, "Do not be afraid--only believe!"

And they came to the house of the ruler of the synagogue and saw a commotion, and [people] weeping and wailing loudly.
