(10) The Lord of hosts.--A second challenge from the reluctant gates serves as the inauguration of the great name by which the Divine nature was especially known under the monarchy. (For its origin and force, see Note on 1Samuel 1:3.)

Verse 10. - Who is this King of glory? The second part of the choir reiterates its question, as though not yet quite understanding. "Who is he, this King of glory?" and the first, slightly varying its answer, replies, The Lord of hosts, he is the King of glory. The epithet, "Lord of hosts" well known at the time (1 Samuel 1:11; 2 Samuel 5:10; 2 Samuel 6:2; 2 Samuel 7:18, 26, 27, etc.), made all clear, and, the gates being thrown open, the ark was brought in, and set in its place in the midst of the tabernacle (2 Samuel 6:17). It has been generally recognized that the reception of the ark into the tabernacle on Mount Zion typified the entrance of our Lord into heaven after his ascension, whence our Church appoints this psalm as one of those to be recited on Ascension Day.

24:7-10 The splendid entry here described, refers to the solemn bringing in of the ark into the tent David pitched for it, or the temple Solomon built for it. We may also apply it to the ascension of Christ into heaven, and the welcome given to him there. Our Redeemer found the gates of heaven shut, but having by his blood made atonement for sin, as one having authority, he demanded entrance. The angels were to worship him, Heb 1:6: they ask with wonder, Who is he? It is answered, that he is strong and mighty; mighty in battle to save his people, and to subdue his and their enemies. We may apply it to Christ's entrance into the souls of men by his word and Spirit, that they may be his temples. Behold, he stands at the door, and knocks, Rev 3:20. The gates and doors of the heart are to be opened to him, as possession is delivered to the rightful owner. We may apply it to his second coming with glorious power. Lord, open the everlasting door of our souls by thy grace, that we may now receive thee, and be wholly thine; and that, at length, we may be numbered with thy saints in glory.Who is this King of glory?.... This is repeated, because of the preceding words, and in order to have a further account of his glorious Person, as follows:

the Lord of hosts, he is the King of glory; he who is the Lord of sabaoth, the Lord of the armies, both of the heavens and the earth; at whose dispose and control all things are in both worlds, above and below: this is the great and glorious Person that condescends to dwell in his churches, and in the hearts of his people; and this honour have his saints.

Selah; on this word; see Gill on Psalm 3:2.
