Yahweh will give the Babylonians control over Egypt just as a person who sells something gives the one who buys it control over that thing. AT: "I will give control of the land to wicked men" (See: [[rc://en/ta/man/translate/figs-metaphor]])
Here "hand of strangers" represents the actions of strangers. "I will cause people from another nation to destroy the land and everything in it" (See: [[rc://en/ta/man/translate/figs-metonymy]])
