When they were come, they went up into an upper room Where they usually held their meetings. The upper rooms, so frequently mentioned in Scripture, were chambers in the highest part of the houses, set apart by the Jews for private prayer. These, on account of their being so retired and convenient, the apostles now used for all the offices of religion. Here all the eleven were assembled, who all continued with one accord in prayer and supplication And that with great intenseness and ardour of soul; with the women Who were formerly mentioned as attending the cross of their Lord, and being early at the sepulchre on the day in which he arose; and Mary the mother of Jesus Mentioned here the last time in the Scriptures; and with his brethren His near kinsmen, who for some time did not believe; probably not till near, or even after, the time of his death.
