Noun gerousia (senate of elders) in the Gospels-Acts

(Translation from NRSV with a few modifications for a more literal meaning)

Acts

5: 21When they heard this, they entered the temple at daybreak and went on with their teaching. When the high priest and those with him arrived, they called together the council and the whole senate of the elders (gerousia) of Israel, and sent to the prison to have them brought.
