ASSEMBLY
1. ekklesia (ἐκκλησία, 1577), from ek, “out of,” and klesis, “a calling” (kaleo, “to call”
, was used among the Greeks of
a body of citizens “gathered” to discuss the affairs of state, Acts 19:39. In the Sept. it is used to
designate the “gathering” of Israel, summoned for any definite purpose, or a “gathering” regarded as representative of the whole nation. In Acts 7:38 it is used of Israel; in 19:32, 41, of
a riotous mob. It has two applications to companies of Christians, (a) to
the whole company of the redeemed throughout the present era, the company of which Christ said, “I will build My Church,” Matt. 16:18, and which is further described as “the Church which is His Body,” Eph. 1:22; 5:23, (b)
in the singular number (e.g., Matt. 18:17, RV marg., “congregation”
,
to a company consisting of professed believers,

in conclusion:
ekklesia, a gathering of people for any reason for a particular purpose.
1. of all true believers, also known as the body of Christ
2. A gathering together of those PROFESSING to be believers. yet back in the NT as well as today, Not all people who confess to be believers are true believers. there are MANY imposters. As john said, they departed from us from who? they church they claimed to be a part of and professed to believe in, but they WERE NEVER OF US, they were never members of the true body of Christ, but they WERE part of the local church.
keep trying my friend. You may get it one day.
