'Rulers' in the Bible

And one of the rulers of the Synagogue, Jairus by name, came, and seeing him, went down at his feet,

And Jesus made them come to him, and said to them, You see that those who are made rulers over the Gentiles are lords over them, and their great ones have authority over them.

But take care: for they will give you up to the Sanhedrins; and in Synagogues you will be whipped; and you will be taken before rulers and kings because of me, for a sign to them.
