Ps 67:18

“It does not escape our notice that some copies have likewise, according to Luke: "How much more shall your heavenly Father give a good gift to them that ask him." This good gift is the grace of the Spirit, which the Lord Jesus shed forth from heaven, after having been fixed to the gibbet of the cross, returning with the triumphal spoils of death deprived of its power, as you find it written: "Ascending up on high he led captivity captive, and gave good gifts to people." And well does he say "gifts," for as the Son was given, of whom it is written: "Unto us a Child is born, unto us a Son is given," so, too, is the grace of the Spirit given. But why should I hesitate to say that the Holy Spirit also is given to us, since it is written: "The love of God is shed forth in our hearts by the Holy Spirit, who is given to us." And since captive hearts certainly could not receive him, the Lord Jesus first led captivity captive, that our affections being set free, he might pour forth the gift of divine grace.”

“But what are we to make of the fact that an eagle often snatches away its prey and often takes the prey belonging to another? But not even in this respect is the Savior unlike the eagle. In a manner of speaking, he indeed took away the prey when he carried mankind to heaven, whom he bore after snatching them away from the jaws of hell; he brought to the heights the captive slave out of his captivity, whom he rescued from the lordship of another, that is, from the devil's power, as it is written in the prophet, "When he ascended on high, he led captivity captive and gave gifts to mankind." At any rate, this sentence is understood in this way, namely, that the Lord by rescuing mankind took captive for himself the captivity of mankind, whom the devil had taken captive for his benefit, and thus, just as he says, he took captivity itself captive and brought it to the heights of the heavens. Therefore, both captivities are designated by the one word, but they are not equal. For the captivity of the devil subjects one to slavery, but the captivity of Christ restores one to freedom.”

“Then there is the apostle Paul: "To each one of us," he says, "is given grace according to the measure of the gift of Christ," and to show that the gift of Christ is the Holy Spirit he went on to add, "That is why it says, he ascended on high, he took captivity captive, he gave gifts to people." But it is public knowledge that when the Lord Jesus had ascended to heaven after his resurrection from the dead he gave the Holy Spirit; and being filled with it those who believed began to speak with the tongues of all people. And do not let it worry you that he says "gifts," not "gift." He was quoting the text from a psalm, and what we read in the psalm is, "you have ascended on high, you have taken captivity captive, you have received gifts among people." This is the reading of most codices, especially the Greek ones, and we have it translated like this from the Hebrew. So the apostle said "gifts" just as the prophet did, not "gift"; but while the prophet said "you have received them among people," the apostle preferred to say "he has given them to people," in order that we might get the fullest meaning from both statements, the one prophetic, the other apostolic, since each has the authority of the divine utterance behind it.”

“Concerning this again he says, "Ascending on high, He led captivity captive, He gave gifts to men." For ascending on high, He led captivity captive, because He absorbed our corruption by the power of His incorruption. And He gave gifts to men, because, sending the Spirit from above, to one He granted the word of wisdom, to another the word of knowledge, to another the grace of powers, to another the grace of healings, to another kinds of tongues, to another the interpretation of speeches. Therefore He gave gifts to men.”
