'Chief Priests and Elders' in the Bible

While He was still speaking, behold, Judas, one of the twelve, came up accompanied by a large crowd with swords and clubs, who came from the chief priests and elders of the people.

Then when Judas, who had betrayed Him, saw that He had been condemned, he felt remorse and returned the thirty pieces of silver to the chief priests and elders,

And while He was being accused by the chief priests and elders, He did not answer.
