This Ps. is generally, and very appropriately, connected with the occasion when David brought up the ark from the house of Obededom to the tent prepared for it on Mt. Zion. It declares the universal sovereignty of God the Creator (Psalms 24:1-2), and describes the character of those who may approach His earthly dwelling (Psalms 24:3-6). Then there follows a twice-repeated scene, in which the gates of Jerusalem are summoned to open, that God, as represented by the ark, may enter; while the warders ask who the approaching conqueror is, and the people reply that He is the Lord of hosts (Psalms 24:7-10).
Psalms 24:1-10
1 The earth is the LORD'S, and the fulness thereof; the world, and they that dwell therein.
2 For he hath founded it upon the seas, and established it upon the floods.
3 Who shall ascend into the hill of the LORD? or who shall stand in his holy place?
4 He that hath clean hands, and a pure heart; who hath not lifted up his soul unto vanity, nor sworn deceitfully.
5 He shall receive the blessing from the LORD, and righteousness from the God of his salvation.
6 This is the generation of them that seek him, that seek thy face, O Jacob.a Selah.
7 Lift up your heads, O ye gates; and be ye lift up, ye everlasting doors; and the King of glory shall come in.
8 Who is this King of glory? The LORD strong and mighty, the LORD mighty in battle.
9 Lift up your heads, O ye gates; even lift them up, ye everlasting doors; and the King of glory shall come in.
10 Who is this King of glory? The LORD of hosts, he is the King of glory. Selah.
