Bible Notes Online - Job 18 - ESV
Commentary

v1-4: Bildad's personal attack continues, tormenting Job's soul, breaking him in pieces (see 19.2). He challenged Job to be angry towards him.

v5-21: A description of the ungodly suffering in this life. Although there is no explicit reference to Job, it is clear that Bildad is referring to him. It may be that Bildad actually addressed the gathered company, describing Job sitting in their midst, 'Come and see the man punished by God.'
