Some translations set each line of poetry farther to the right than the rest of the text to make it easier to read. The ULB does this with the poetic song in 1:2-18.
In this chapter, it is unclear whether these prophecies concern the fall of Jerusalem, the coming of the Messiah or the day of the Lord. It is possible that the prophecies reference more than one period of time.
