'Inner' in the Bible

Receiving such orders, he threw them in the inner cell and fastened their feet in the stocks.

shouting, "Men of Israel, help! This is the man who teaches everyone everywhere against our people, our law, and this sanctuary! Furthermore he has brought Greeks into the inner courts of the temple and made this holy place ritually unclean!"

(For they had seen Trophimus the Ephesian in the city with him previously, and they assumed Paul had brought him into the inner temple courts.)
