Charles Ellicott Commentary Psalms 24:1

"The earth is Jehovah`s, and the fulness thereof; The world, and they that dwell therein." — Psalms 24:1 (ASV)

The Lord’s. —The majesty of Jehovah as Lord of the universe is a reason for the psalmist to insist on rectitude and sincerity in those who become His worshippers. St. Paul uses the same truth, referring to this passage (1 Corinthians 10:26), to show that all things are innocent and pure to the pure; so that a Christian (apart from a charitable regard for the weak) may eat whatever is sold in the market, without troubling himself to inquire whether it has been offered to idols or not.
