BBC: Psalm 8:5-9
5 Yet you have made him a little lower than the heavenly beings
and crowned him with glory and honor.
6 You have given him dominion over the works of your hands;
you have put all things under his feet,
7 all sheep and oxen,
and also the beasts of the field,
8 the birds of the heavens, and the fish of the sea,
whatever passes along the paths of the seas.
9 O Lord, our Lord,
how majestic is your name in all the earth!
Returning to this psalm, David reflects back on the lowliness of man. Though seemingly negative previous (v. 4). But deeper reflection is that man has been placed in a position of supreme power and authority in creation. This portion of the psalm is quoted in the book of Hebrews and is applied directly to Christ (Heb 2:5-8).
This passage is similar in content to the eschatological vision of Paul (1 Cor 15:20-28). But these commands and exaltation are rooted primarily in the creation account(s) of Adam (Gen 1:28-30) and Noah (Gen 9:1-3). It is this placement of man over creation and the proper working out of this authority that brings the majestic glory of God throughout the earth. This fulfillment is not left in the hands of sinful men but is fully satisfied and accomplished in Jesus Christ.
