'Rulers' in the Bible

Pilate summoned the chief priests and the rulers and the people,

Now the people stood by, watching; but even the rulers ridiculed and sneered at Him, saying, “He saved others [from death]; let Him save Himself if He is the Christ (the Messiah, the Anointed) of God, His Chosen One.”

and how the chief priests and our rulers handed Him over to be sentenced to death, and crucified Him.
