Acts 5:11 New International Version

Noun - Accusative Feminine Singular
Strong's Greek 1577: From a compound of ek and a derivative of kaleo; a calling out, i.e. a popular meeting, especially a religious congregation.
"Church" was a new concept at that time. Outside of the Bible, did the word ἐκκλησία mean a congregation of a Greek religion?
Acts 19:39 If there is anything further you want to bring up, it must be settled in a legal assembly [ἐκκλησίᾳ].
Here the same lexeme refers to a non-religious body of people. What is the meaning of the Greek word ἐκκλησία at the time of Jesus before local churches appeared?
