(8) But ye shall receive power.--The use of the same English noun for two different Greek words is misleading, but if "authority" be used in Acts 1:7 then "power" is an adequate rendering here. The consciousness of a new faculty of thought and speech would be to them a proof that the promise of the Kingdom had not failed.

Ye shall be witnesses unto me.--The words, which are apparently identical with those of Luke 24:48, strike the key-note of the whole book. Those which follow correspond to the great divisions of the Acts--Jerusalem, Acts 1, 7; Judaea, 9:32, 12:19; Samaria, 8; and the rest of the book as opening the wider record of the witness borne "to the uttermost parts of the earth." And this witness was two-fold: (1) of the works, the teachings, and, above all, of the Resurrection of Jesus; (2) of the purpose of the Father as revealed in the Son. The witness was to be, in language which, though technical, is yet the truest expression of the fact, at once historical and dogmatic.

Verse 8. - When for after that, A.V.; my witnesses for witnesses unto me, A.V. and T.R.; Samaria for in Samaria, A.V. Ye shall receive power (δύναμιν); a word sped-ally used of the power of the Holy Spirit (see Acts 6:8). "Jesus returned in the power of the Spirit" (Luke 4:14; see too Luke 24:49); "God anointed Jesus of Nazareth with the Holy Ghost and with power" (Acts 10:38); "Through the power of the Holy Ghost" (Romans 15:13); "The demonstration of the Spirit and of power" (1 Corinthians 2:4); "Strengthened with might (δυνάμει) by his Spirit" (Ephesians 3:16); "The powers of the world to come" (Hebrews 6:6). My witnesses. This function of the apostles, to be witnesses of Christ, is one much insisted upon in Scripture. So we read in ver. 22, "Of these must one become ['be ordained,' A.V.] a witness with us of his resurrection." So again in Acts 10:40-42, "God... showed him openly; not to all the people, but unto witnesses chosen before of God, even to us.... And he commanded us to testify," etc. (see also Vers. 39 and 42 of the same chapter; Acts 13:31; Luke 24:48; Acts 4:33; Acts 13:31; Acts 22:15, 18, 20; Acts 26:16; 1 Peter 5:1; 1 John 1-3, 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.But ye shall receive power,.... From on high, with which they were to be endured, Luke 24:49 meaning the power of the Holy Ghost, strength from him to preach the Gospel, and work miracles in confirmation of it, and courage and greatness of mind, amidst all reproaches and persecutions, to face and oppose their enemies, profess the name of Christ, abide by his truths and ordinances, make their way through all opposition and difficulties, and spread the Gospel all over the world; for intend of enjoying worldly ease, honour, wealth, and riches, they were looking for, our Lord gives them to understand that they must expect labour, service, afflictions, and trials, which would require power and strength, and which they should have:

after that the Holy Ghost shall come upon you; from above, from heaven, as he did, and sat upon them in the form of cloven tongues, and of fire; upon which they were filled with knowledge and zeal, with strength and courage, and with all gifts and abilities necessary for their work:

and ye shall be witnesses unto me; of the person of Christ, of his deity and sonship, of his incarnation, his ministry, and his miracles, of his suffering and death, of his resurrection from the dead, and his ascension to heaven. This was to be their work, and what belong to them, and not to enquire about a temporal kingdom, and the setting up of that, and the times and seasons of it; their business was to testify of the sufferings of Christ, and the glory that followed, and to preach a crucified Jesus, as the only Saviour of lost sinners: and this

both in Jerusalem, the "metropolis" of the nation, and there, in the first place, where such dwelt who had been concerned in the crucifixion of Christ, many of whom were to be called by grace, and converted through their ministry:

and in all Judea; that part of the land of Israel which was distinct from Samaria and Galilee, and from beyond Jordan; where churches were to be planted, as afterwards they were; see Acts 9:31.

And in Samaria; where Christ had before forbid his disciples to go; but now their commission is enlarged, and they are sent there; and here Philip went upon the persecution raised against the church at Jerusalem, and preached Christ with great success, to the conversion of many; and hither Peter and John went to lay their hands on them, and confirm them; see Acts 8:5.

and unto the uttermost part of the earth; throughout the whole world, whither the sound of the apostles, and their words went, Romans 10:18.
