(10) Two men stood by them in white apparel.--Better, were standing, the appearance being sudden, and their approach unnoticed. The forms were such as those as had been seen at the portals of the empty sepulchre, bright and fair to look upon, and clad in white garments, like the young priests in the Temple. (See Note on Luke 1:12.)

Verse 10. - Were looking for looked, A.V. ; into for toward, A.V.; went for went up, A.V. Two men. St. Luke describes them according to their appearance. They were really angels. In like manner, in Joshua 5:13 we read, "There stood a man over against him;" and in Genesis 18:2, 16; Genesis 19:10, 12, 16, we read of "the men;" and in Judges 13:6, 8, 10, 11, of "the man of God;" the persons spoken of in all these cases being angels (comp. Daniel 3:25; Daniel 8:15, 16; Daniel 9:21, etc.; Zechariah 1:8, 10; Mark 16:5; Luke 24:4). Gabriel, too, means "man of God." In white apparel, typical of perfect holiness, and of the glory which belongs to the inhabitants of heaven (comp. Daniel 10:5, 6; Matthew 17:2; Matthew 28:3; Mark 9:3; Mark 16:5; Luke 24:4; Revelation 7:9, 13; Revelation 3:5, 18; Revelation 4:4; Revelation 6:11; Revelation 19:8, etc.).

1:6-11 They were earnest in asking about that which their Master never had directed or encouraged them to seek. Our Lord knew that his ascension and the teaching of the Holy Spirit would soon end these expectations, and therefore only gave them a rebuke; but it is a caution to his church in all ages, to take heed of a desire of forbidden knowledge. He had given his disciples instructions for the discharge of their duty, both before his death and since his resurrection, and this knowledge is enough for a Christian. It is enough that He has engaged to give believers strength equal to their trials and services; that under the influence of the Holy Spirit they may, in one way or other, be witnesses for Christ on earth, while in heaven he manages their concerns with perfect wisdom, truth, and love. When we stand gazing and trifling, the thoughts of our Master's second coming should quicken and awaken us: when we stand gazing and trembling, they should comfort and encourage us. May our expectation of it be stedfast and joyful, giving diligence to be found of him blameless.And while they looked steadfastly toward heaven,.... For though he was taken out of their sight by the cloud, they kept looking upwards, and after him, if they could see him again, or any more of him:

as he went up; they looked up to heaven after him, as he went up from the earth, before the cloud took him out of their sight; and still they continued looking, as the cloud carried him up, until it was out of the reach of their sight, being willing to see the last of him in this way:

behold, two men stood by them in white apparel; that is, two angels in the form of men; it being usual with them to appear in human form: these on a sudden appeared and stood on the earth just by them; though the Ethiopic version renders it, "they stood above them", as if they were in the air over their heads; and they appeared in white apparel, as the angel at the sepulchre in Matthew 28:2 which was a symbol both of their purity and holiness, and of their lustre and glory. The Ethiopic version renders it, "they were clothed with lightning"; they appeared in such a dazzling form, that it looked as if they were covered with lightning; as the angel that appeared at Christ's resurrection, his countenance is said to be as lightning; which must at once fix the attention of the disciples to them, and strike them with surprise: hence a "behold" is prefixed to this: and hereby they knew that they were not common and ordinary men, or mere men, but angels in such a form.
