'Elders' in the Bible

(The Pharisees and indeed all the Jewish people don't eat unless they wash their hands properly, following the tradition of their elders.

So the Pharisees and the scribes asked Jesus, "Why don't your disciples live according to the tradition of the elders? Instead, they eat with unclean hands."

Then he began to teach them that the Son of Man would have to suffer a great deal and be rejected by the elders, the high priests, and the scribes. Then he would be killed, but after three days he would rise again.

When the high priests and elders heard this, they began to look for a way to kill him, because they were afraid of him, since the whole crowd was amazed at his teaching.

Then they went into Jerusalem again. While Jesus was walking in the Temple, the high priests, the scribes, and the elders came to him

Just then, while Jesus was still speaking, Judas, one of the Twelve, arrived. A crowd armed with swords and clubs was with him. They were from the high priests, the scribes, and the elders.

Then they took Jesus to the high priest. All the high priests, elders, and scribes had gathered together.

As soon as it was morning, the high priests convened a meeting with the elders and scribes and the whole Council. They bound Jesus with chains, led him away, and handed him over to Pilate.
