'Rulers' in the Bible

One day--it was a Sabbath--He was taking a meal at the house of one of the Rulers of the Pharisee party, while they were closely watching Him.

Then calling together the High Priests and the Rulers and the people, Pilate said,

and the people stood looking on. The Rulers, too, repeatedly uttered their bitter taunts. "This fellow," they said, "saved others: let him save himself, if he is God's Anointed, the Chosen One."

and how our High Priests and Rulers delivered Him up to be sentenced to death, and crucified Him.
