'Chief Priests and Elders' in the Bible

While he yet spake, Lo, Judas, one of the twelve, came: and with him a great multitude with swords and staves, which were sent from the chief priests and elders of the people.

Then when Judas, which betrayed him, saw that he was condemned, he repented himself; and brought again the thirty plates of silver to the chief priests and elders,

And when he was accused of the chief priests and elders, he answered nothing.
