Brethren (adelfwn). Codex Bezae has "disciples."
Multitude of persons (oxlov onomatwn). Literally, multitude of names. This Hebraistic use of onoma=person occurs in the LXX (Numbers 1:2; Numbers 18:20; Numbers 3:40, Numbers 3:43; Numbers 26:53) and in Revelation 3:4; Revelation 11:13.
Together (epi to auto). The word "gathered" is not in the Greek here, but it does occur in Matthew 22:34 and that is undoubtedly the idea in Luke 17:35 as in Acts 2:1, Acts 2:44, Acts 2:47; I Corinthians 11:20; I Corinthians 14:23. So also here. They were in the same place (to auto).
About a hundred and twenty (wv ekaton eikosi). A crowd for "the upper room." No special significance in the number 120, just the number there.
