24:1 the Lord’s. On His universal ownership, cf. Ex 19:5; Dt 10:14; Pss 50:12; 89:11; in the NT, cf. 1Co 3:21, 23.
24:2 This is a poetic, not a scientific, picture of creation (cf. Ge 1:9, 10; 7:11; 49:25; Ex 20:4; Dt 33:13; Job 26:10; Pss 74:13; 136:6; 2Pe 3:5).

24:1–2 The Lord Is Creator and Owner of All. The Lord, the covenant God of Israel, is the one who founded the world (cf. Gen. 1:1–2:3, where he is called God, the transcendent Creator). The focus here is on the earth as the dry land, where human beings dwell, as distinguished from the waters (cf. Gen. 1:9–10). Paul quotes Ps. 24:1 in 1 Cor. 10:26 to explain that since God owns everything, foods are included, and thus may be enjoyed without qualms.

24:1 The earth is the Lord’s. God created and sustains the whole earth; it belongs to Him. Paul cites this verse to establish the principle that there is no food, even things offered to pagan idols, which is unlawful for Christians to eat (1 Cor. 10:25, 26).
24:2 he has founded it upon the seas. This section reflects the creation account in Gen. 1. However, the sea is also a poetic image for evil. Throughout the psalms and the prophets, God is pictured as winning a victory over the sea (Ps. 29:10, 11; 77:16–20; 104:5–9; Nah. 1:4; Dan. 7).
