Деяния 1:9

while they beheld, he was taken up--See on Luk 24:50-53. Lest it should be thought He had disappeared when they were looking in some other direction, and so was only concluded to have gone up to heaven, it is here expressly said that "while they were looking He was taken up, and a cloud received Him out of their sight." So Elijah, "If thou see me when I am taken from thee" (Kg2 2:10); "And Elisha saw it" (Act 1:12). (See on Luk 9:32.)

The inspired historian begins his narrative of the Acts of the Apostles, I. With a reference to, and a brief recapitulation of, his gospel, or history of the life of Christ, inscribing this, as he had done that, to his friend Theophilus (Act 1:1, Act 1:2). II. With a summary of the proofs of Christ's resurrection, his conference with his disciples, and the instructions he gave them during the forty days, of his continuance on earth (Act 1:3-5). III. With a particular narrative of Christ's ascension into heaven, his disciples' discourse with him before he ascended, and the angels' discourse with them after he ascended (Act 1:6-11). IV. With a general idea of the embryo of the Christian church, and its state from Christ's ascension to the pouring out of the Spirit (Act 1:12-14). V. With a particular account of the filling up of the vacancy that was made in the sacred college by the death of Judas, by the electing of Matthias in his room (Act 1:15-26).
