They went up into the upper room — The upper rooms, so frequently mentioned in Scripture, were chambers in the highest part of the house, 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. Matthew 10:2; Mark 3:14; Luke 6:13.
