Job 37:19

Teach us what we shall say unto him? - Thou pretendest to be so very wise, and to know every thing about God, pray make us as wise as thyself, that we may be able to approach with thy boldness the Sovereign of the world; and maintain our cause with thy confidence before him. As for our parts, we are ignorant; and, on all these subjects, are enveloped with darkness. Mr. Good translates: -

"Teach us how we may address him,

When arrayed in robes of darkness."

It is a strong and biting irony, however we take it.
