Job 33:5

If thou canst answer me, set thy words in order before me, stand up.

If you can, answer me; Set your words in order before me, and stand forth.

If thou canst, answer thou me; Set `thy words' in order before me, stand forth.

If thou art able -- answer me, Set in array before me -- station thyself.

Refute me if you can; prepare your case and confront me.
