The prophet speaks of Yahweh creating the heavens and the earth as if the heavens and earth were fabric which Yahweh stretched out. (See: [[rc://en/ta/man/translate/figs-metaphor]])
These phrases mean basically the same thing and emphasize that Yahweh gives life to every person. The word "breath" is a metonym for life. AT: "gives life to the people who live on the earth" (See: [[rc://en/ta/man/translate/figs-parallelism]] and [[rc://en/ta/man/translate/figs-metonymy]])
