Charles Ellicott Commentary Acts 1:4

"and, being assembled together with them, he charged them not to depart from Jerusalem, but to wait for the promise of the Father, which, [said he], ye heard from me:" — Acts 1:4 (ASV)

And, being assembled together with them.—The manuscripts present two forms of the participle: one with the meaning given in the English version; the other, though an inferior reading, with the sense of “dwelling together with” the disciples. The Vulgate, convescens, “eating with,” probably rests on a mistaken etymology of the Greek term. The whole verse is in substance a repetition of Luke 24:49 (see the notes on that verse).
