Vine's Expository Dictionary of NT Words

1: γερουσία

(Strong's #1087 — Noun Feminine — gerousia — gher-oo-see'-ah )

"a council of elders" (from geron, "an old man," a term which early assumed a political sense among the Greeks, the notion of age being merged in that of dignity), is used in Acts 5:21 , apparently epexegetically of the preceding word sunedrion, "council," the Sanhedrin.
