'Ruler of the Synagogue' in the Bible

Some time after, a person nam'd Jairus, a ruler of the synagogue, came to Jesus, and upon his knees desired him to come to his house:

While he was speaking, somebody came from the ruler of the synagogue's house, who said to him, your daughter is dead; 'tis in vain to importune the master any farther.

but the ruler of the synagogue being highly incensed at Jesus's healing on the sabbath-day, said to the people, there are six days for work, you should come therefore for cure on those days, and not on the sabbath.
