Senate

[ 1,,G1087, gerousia ]
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.
