Zephaniah 3.10, Look With Me, From Beyond the Rivers of Cush

Zephaniah 3.9 is actually envisioning the reversal of past judgment, and it intentionally uses one people group, Cush, as the only example of global restoration. Zephaniah envisions the worshipers gathering to Yahweh at his restored Edenic sanctuary to give him offerings. It's as if the descendants of those once exiled from Eden and scattered from Babylon are now following the rivers of life back to their source for fellowship with the great king.
