The earth is the LORD's, and the fulness thereof; the world, and they that dwell therein.
This psalm refers primarily to David's bringing the ark up to Zion (2 Samuel 6:1-15). This is the oldest of the Introit psalms (i:e., sung at the Temple entrance). God's absolute ownership of the world (as in Psalms 15:1-5), introduces the main subject. Zion's ancient doors typify heaven's everlasting doors (Psalms 24:1-10). God's ownership of the world, based on His creation of it (Psalms 24:1-2); who alone may ascend and dwell with so holy a God in His sanctuary?-The pure alone (Psalms 24:3-6); at the ark's entrance, the gates are called upon to exult at the entering in of the Lord of glory (Psalms 24:7-10). The earth is the Lord's. God makes a preliminary provision for the honour of His Divine Majesty, which might seem somewhat compromised by His manifesting His presence in a tabernacle made with hands. So in Isaiah 66:1, introductory to His manifestation in the millennial Zion. So at the dedication of Solomon's temple (1 Kings 8:27). The Lord's absolute ownership of the earth is utterly incompatible with the worship of any outward or inward idols (1 Corinthians 10:28).
The world, х teebeel (H8398), the habitable world, oikoumenee; from yaabal (H2986), to bear fruit] is viewed in reference to its inhabitants, as "the earth" has with it "the fullness thereof" - i:e, all that it contains; all that fills it. Compare Isaiah 42:10; Amos 6:8 х pleerooma (G4138)]. The Septuagint, prefix to the psalm 'On the first day of the week' х tees (G3588) mias (G3391) toon (G3588) sabbatoon (G4521)]. It was sung usually on that day. So the rabbis say: thus, with unconscious propriety, the Jewish Church connected it with our Christian Sabbath. Christ, as the Instrumental Creator, is Proprietor of the earth. In spite of Satan's temporary usurpation, owing to Adam's forfeiture of man's inheritance, Christ is Lord of the earth, and, as the Second Adam, shall restore to man his rightful possession (Psalms 8:1-9; Colossians 1:16-19).
