Job challenges them to look at him (Job 6:28-6:30)

“But now,

Be pleased to look at me.

I will not lie to your face.

Turn!

I pray,

Let no wrong be done.

Turn now!

My vindication is at stake.

Is there any wrong on my tongue?

Cannot my taste discern calamity?”

In very strong terms, Job challenged his 3 friends to look him in the face. Had he been deceptive? Had he lied? Why were they accusing him of wrong doing?
