And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, {i} until ye be endued with power from on high.

(i) Until the Holy Spirit comes down from heaven upon you.

Tarry ye. They were not to begin the great work until the endowment from on High came.

Jamieson-Fausset-Brown Bible Commentary

49. I send-the present tense, to intimate its nearness.

promise of my Father-that is, what My Father hath promised; the Holy Ghost, of which Christ is the authoritative Dispenser (Joh 14:7; Re 3:1; 5:6).

endued-invested, or clothed with; implying, as the parallels show (Ro 13:14; 1Co 15:53; Ga 3:27; Col 3:9, 10), their being so penetrated and acted upon by conscious supernatural power (in the full sense of that word) as to stamp with divine authority the whole exercise of their apostolic office, including, of course, their pen as well as their mouth.

Matthew Henry's Concise Commentary

24:36-49 Jesus appeared in a miraculous manner, assuring the disciples of his peace, though they had so lately forsaken him, and promising spiritual peace with every blessing. Many troublesome thoughts which disquiet our minds, rise from mistakes concerning Christ. All the troublesome thoughts which rise in our hearts at any time, are known to the Lord Jesus, and are displeasing to him. He spake with them on their unreasonable unbelief. Nothing had passed but what was foretold by the prophets, and necessary for the salvation of sinners. And now all men should be taught the nature and necessity of repentance, in order to the forgiveness of their sins. And these blessings were to be sought for, by faith in the name of Jesus. Christ by his Spirit works on the minds of men. Even good men need to have their understandings opened. But that we may have right thoughts of Christ, there needs no more than to be made to understand the Scriptures.
