The Scofield Bible Commentary, by Cyrus Ingerson Scofield, [1917], at sacred-texts.com
Who shall
The order is:
(1) the declaration of title, "the earth is the Lord's" (Psa 24:1); (Psa 24:2).
(2) Who shall rule the earth? (Psa 24:3-6). It is a question of worthiness, and no one is worthy but the Lamb.
Compare (Dan 7:13); (Dan 7:14); (Rev 5:3-10); (Mat 25:31).
(3) The King of glory takes the throne of earth (Psa 24:7-10).
See Psalm 40, next in order of the Messianic Psalms.
