'Ruler of the Synagogue' in the Bible

And, behold, there came a man named Jairus, and he was a ruler of the synagogue: and he fell down at Jesus' feet, and besought him that he would come into his house:

While he yet spoke, there came one from the ruler of the synagogue's house, saying to him, your daughter is dead; trouble not the Teacher.

And the ruler of the synagogue answered with indignation, because Jesus had healed on the sabbath day, and said unto the people, There are six days in which men ought to work: in them therefore come and be healed, and not on the sabbath day.
