Psalms 24:1

The earth [is] the Lord's, and the fulness thereof
The whole universe, all the terraqueous globe, both land and water, and the circumambient air, and all that is therein; the fishes of the sea, the fowls of the air, the beasts of the field, all plants and vegetables that spring out of the earth, and metals and minerals in the bowels of it; all which are the riches of the Lord the earth is full of, ( Psalms 104:24 ) ; see ( Psalms 50:10-12 ) ;

the world, and they that dwell therein;
the habitable world, and the dwellers on it, rational and irrational. These words may be interpreted of Christ, who is Lord of all; he made the world, and has a right and claim to all things in it; for the same person is here spoken of as in the preceding psalm, under the character of a shepherd; and this shows him to be very fit and proper for such an office, seeing he cannot fail of feeding and protecting his sheep; nor can they want any good thing, since the fulness both of nature and of grace is with him; and hence it is that all things are theirs, whether the world, or things present, or things to come; and though they seem to have nothing, yet possess all things, they possessing him whose all things are. The apostle makes use of this passage of Scripture, to prove, explain, and direct in the use of Christian liberty, with respect to the free use of creatures, they all being the Lord's; and therefore good, and to be received with thanksgiving: and yet, inasmuch as there is a variety of them, such should be abstained from, when to use them serves to embolden evil men in their wicked ways, or offend and grieve weak Christians, ( 1 Corinthians 10:25 1 Corinthians 10:26 1 Corinthians 10:28 ) .
