The New John Gill Exposition of the Entire Bible1 Corinthians 16:20
All the brethren greet you…
Either the brethren, the
members of the church at Ephesus; or the apostle's brethren in the
ministry, that were along with him, as Sosthenes and others; or the
brethren that were come to him from Corinth, namely Stephanas,
Fortunatus, and Achaicus:
greet ye one another with an holy kiss; (See Gill on 16:16).
