The ULB indents the lines of this chapter because it is a poem. This chapter is a continuation of Job's statement and it is directly addressed to Yahweh.
In this chapter, Job presents his case to Yahweh that he is upright and not guilty of the sins he is being accused of. (See: [[rc://en/tw/dict/bible/kt/upright]], [[rc://en/tw/dict/bible/kt/guilt]] and [[rc://en/tw/dict/bible/kt/sin]])
