'Chief Priests and Elders' in the Bible

Barely had he spoken these words when Judas, one of the Twelve, appeared, accompanied by a great crowd of men with swords and staves, from the chief priests and elders of the people.

Then when Judas, his betrayer, saw that he was condemned, he repented and brought back the thirty pieces of silver to the chief priests and elders.

"It is as you say," answered Jesus; but while he was being accused by the chief priests and elders, he answered nothing.

Then they took Jesus to the high priest, and all the chief priests and elders and Scribes came with him.
