And they [i.e., the apostles] were all filled with [the power of] the Holy Spirit and began to speak ["the mighty accomplishments of God," See verse 11] in different languages, as the Holy Spirit gave them the ability.

Then Peter, filled with the Holy Spirit, addressed them, saying, "Rulers and elders of the people,

Brothers, select from among you seven men with good reputations, who are full of the Holy Spirit and wisdom, whom we can appoint to take care of this matter.

But Saul, [now] also called Paul, being filled with [the power of] the Holy Spirit, looked at him intently

Looked

And while they gazed up into the sky as He ascended, suddenly two men wearing white clothing appeared beside them

I know a man in [fellowship with] Christ who, fourteen years ago, was taken [literally, "snatched"] up to the third heaven. [Note: The first heaven would be where birds fly; the second where the stars are; and the third where God is]. (I do not know whether he was in his physical body or whether it was an "out-of-the-body" experience, but God knows). [Note: Paul is obviously telling about a personal experience. See verse 7].

After [seeing all] these things, I looked, and there in heaven I saw [a vision of] an open door, and the voice I had first heard speaking to me like [the sound of] a trumpet [See 1:10], said, "Come up here [i.e., to heaven], and I will show you the things which must happen after these things [i.e., the things just revealed]."

And saw

Isaiah had said these things because he saw the [coming] glory of Jesus, and [so] was speaking about Him.

For God, who said [Gen. 1:3], "Light will shine out of darkness," has [also] shone in our hearts to provide [us with] the light of the knowledge of God's splendor [as it shines] on the face of Christ. [Note: This allusion to "splendor shining on Christ's face" may be a continuation of the analogy used in 3:13].

For Jesus had received honor and glory from God, the Father, when [God's] voice came to Him from the Majestic Glory saying, "This is my dearly loved Son, and I am very pleased with Him."

It had the splendor of God [shining from it], and was as brilliant as a very precious stone, as crystal-clear as jasper.

Standing

And if I go to prepare a place for each of you, I will return to take all you to [be with] me, so that you also will be where I am.

This Son expresses the radiance of God's splendor and represents His very Being, and He sustains everything by His powerful word. After He had provided cleansing for [man's] sins, He sat down at the right side of the Majesty [i.e., God] on high [i.e., in heaven].

Now this is the main point [or, the summary] of what we are saying: We have such a head priest [i.e., as described in chapter 7] who sat down at the right side of the throne of the Majesty [i.e., God] in heaven.
