Expositor's Bible Commentary Commentary Acts 1:10

"And while they were looking stedfastly into heaven as he went, behold, two men stood by them in white apparel;" — Acts 1:10 (ASV)

Luke describes the disciples as “looking intently up [a favorite word of Luke] into the sky as he was going.” They were soon challenged by a double message from two angels “dressed in white.” (1) The Jesus whom the disciples had known now had a heavenly existence (cf. the double use of the phrase “into heaven”). (2) The same Jesus they had known would return also enveloped in the cloud of the divine presence and glory (cf. Matthew 24:30; 26:64; Mark 13:26; Mark 14:62).
