He hath made the earth by his power, he hath established the world by his wisdom, and hath stretched out the heaven by his understanding.

Jamieson-Fausset-Brown Bible Commentary

15-19. Repeated from Jer 10:12-16; except that "Israel" is not in the Hebrew of Jer 51:19, which ought, therefore, to be translated, "He is the Former of all things, and (therefore) of the rod of His inheritance" (that is, of the nation peculiarly His own). In Jer 10:1-25 the contrast is between the idols and God; here it is between the power of populous Babylon and that of God: "Thou dwellest upon many waters" (Jer 51:13); but God can, by merely "uttering His voice," create "many waters" (Jer 51:16). The "earth" (in its material aspect) is the result of His "power"; the "world" (viewed in its orderly system) is the result of His "wisdom," &c. (Jer 51:15). Such an Almighty Being can be at no loss for resources to effect His purpose against Babylon.

Matthew Henry's Concise Commentary

51:1-58 The particulars of this prophecy are dispersed and interwoven, and the same things left and returned to again. Babylon is abundant in treasures, yet neither her waters nor her wealth shall secure her. Destruction comes when they did not think of it. Wherever we are, in the greatest depths, at the greatest distances, we are to remember the Lord our God; and in the times of the greatest fears and hopes, it is most needful to remember the Lord. The feeling excited by Babylon's fall is the same with the New Testament Babylon, Re 18:9,19. The ruin of all who support idolatry, infidelity, and superstition, is needful for the revival of true godliness; and the threatening prophecies of Scripture yield comfort in this view. The great seat of antichristian tyranny, idolatry, and superstition, the persecutor of true Christians, is as certainly doomed to destruction as ancient Babylon. Then will vast multitudes mourn for sin, and seek the Lord. Then will the lost sheep of the house of Israel be brought back to the fold of the good Shepherd, and stray no more. And the exact fulfilment of these ancient prophecies encourages us to faith in all the promises and prophecies of the sacred Scriptures.
