'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 to come into his house;

While he yet spake, there cometh one from the ruler of the synagogue's house , saying, Thy daughter is dead; trouble not the Teacher.

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