This chapter is a continuation of the material in the previous chapter. Some translations indent each line of poetry to make it easier to read. The ULB does this with the poetry in 3:1-26, which is a vision Isaiah receives. These are the words of Yahweh.
This chapter is structured as a judgment against the Jews. God is acting as a judge reading the list of convictions against them and then he reads the judgment. (See: [[rc://en/tw/dict/bible/kt/judge]])
#### Special concepts in this chapter ####
##### Exile #####
While the previous part of the prophecy in chapter 2 discussed the last days, this part of the prophecy predicts the exile of Judah to Babylon. (See: [[rc://en/tw/dict/bible/kt/prophet]] and [[rc://en/tw/dict/bible/kt/lastday]])
