Some translations set poetry farther to the right than the rest of the text to show that it is poetry. The ULB does this with the poetry in this chapter.
This chapter pictures a time when Israel will be fully restored to Yahweh. They will be everything Yahweh intended them to be. All the nations will look to Israel and acknowledge her special relationship to Yahweh. (See: [[rc://en/tw/dict/bible/kt/restore]])
