Charles Ellicott Commentary 1 Corinthians 6:5

"I say [this] to move you to shame. What, cannot there be [found] among you one wise man who shall be able to decide between his brethren," — 1 Corinthians 6:5 (ASV)

I speak to your shame.—Better, I say this to cause you to feel ashamed. From the latent irony of the previous words, the Apostle turns to ask solemnly whether it is true that in the whole Christian community at Corinth, which boasted of its superior wisdom, not even one man is to be found sufficiently esteemed for his wisdom to be trusted by the brothers to settle their disputes.

Shall be able to judge. . . .—Better, shall be able to arbitrate, in contrast to the “going to law” of the next verse, as the words for these two expressions are different in the original.
