'Ruler of the Synagogue' in the Bible

And lo! there came a man, whose name was Jairus, and, the same, was, a ruler of the synagogue, - and, falling down near the feet of Jesus, he began beseeching him to enter into his house;

But, Crispus, the ruler of the synagogue, believed in the Lord, with all his house. And, many of the Corinthians, hearing, were believing, and being immersed.

But they all, laying hold of Sosthenes the ruler of the synagogue, began to strike him before the judgment-seat; and, for none of these things, did Gallio care.
