Ezekiel 38:3

How have you counselled [him that has] no wisdom ?
&c.] A man deprived of wisdom has need of counsel, and it should be given him; and he does well both to ask and take it; and be it so, as if Job should say, that I am the foolish and unwise creature you take me to be, what counsel and advice have you given me? what a wise counsellor have you shown yourself to be? or rather, what a miserable part have you acted under this character?

and [how] have you plentifully declared the thing as it is ?
the thing in controversy, set it forth in a clear light, and in a copious manner, when he had not said one word about it, namely, concerning the afflictions of the godly, and the prosperity of the wicked; thus jeering at him, and laughing at the short reply he had made, and which was nothing to the purpose.
