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.
This chapter prophesies concerning a future time of peace and restoration. It is unlikely to have been fulfilled in Isaiah's day. (See: [[rc://en/tw/dict/bible/other/restore]], [[rc://en/tw/dict/bible/kt/prophet]] and [[rc://en/tw/dict/bible/kt/fulfill]])
