'Ruler' in the Bible

The scribes who had come down from Jerusalem said, “He has Beelzebul in Him!” and, “He drives out demons by the ruler of the demons!”

While he yet spake, there came from the ruler of the synagogue's house certain which said, Thy daughter is dead: why troublest thou the Master any further?

As soon as Jesus heard the word that was spoken, he saith unto the ruler of the synagogue, Be not afraid, only believe.

And he cometh to the house of the ruler of the synagogue, and seeth the tumult, and them that wept and wailed greatly.
