Luke 24:49 - Matthew Poole's English Annotations on the Holy Bible

It is questioned by none, but by the promise of the Father our Lord meaneth the promise of the Spirit, as it came down in the days of Pentecost. This effusion of the Spirit was promised under the Old Testament, Isaiah 44:3 Jeremiah 31:33 Ezekiel 36:27; most eminently, Joel 2:28, the apostle himself interpreting this prophecy, Acts 2:16-18. See also Acts 1:8, where the fulfilling of this promise of the Father, as it is called Acts 1:4, is put before and ye shall be witnesses unto me, both in Jerusalem, and in Judea and in Samaria; and is also expounded by, But ye shall receive power, after the Holy Ghost is come upon you. Our Lord also had said, I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever. 1 Thessalonians 14:16. In this text he saith, that he will send him; so also 1 Thessalonians 15:26 1 Thessalonians 16:7; thereby confirming his disciples in this, that he was equal with the Father, and that the Holy Ghost was sent by the Father and him, yet sent by the Father upon the prayer of the Son, and in his name, 1 Thessalonians 14:16,26. This Holy Spirit is also called, power from on high; the power of the Highest, Luke 1:35. But here the gifts of the Holy Ghost may be understood, as also in Acts 1:8, where it is said this power should be received after that the Holy Ghost should come upon them: until this time should come, which was in the days of Pentecost, Acts 2:1, the disciples were bound to stay at Jerusalem, which accordingly they did. And we may from hence conclude, that these words of our Saviour were spoken to his disciples after his appearance to them in Galilee, (of which Luke saith nothing), which was the place where (as most think) he was seen of above five hundred brethren at once, 1 Corinthians 15:6.
