Jamieson, Fausset and Brown on Jeremiah 51:15-19

15-19. Repeated from Jr 10:12-16; except that "Israel" is not in the Hebrew of Jr 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 Jr 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" (Jr 51:13); but God can, by merely "uttering His voice," create "many waters" (Jr 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. (Jr 51:15). Such an Almighty Being can be at no loss for resources to effect His purpose against Babylon.
