Some translations prefer to set apart extended quotations, prayers or songs. The ULB and many other English translations indent the lines of this chapter, which is an important quotation.
Many scholars believe this chapter prophesies that Gentiles will be able to come to a saving faith in Yahweh. At this time, the Israelites believed that only an Israelite could be saved. (See: rc://en/tw/dict/bible/kt/prophet, rc://en/tw/dict/bible/kt/save and rc://en/tw/dict/bible/kt/faith)
