Who is weak, and I am not weak? who is offended, and I burn not?
Ver. 29. Who is weak] By passion.
And I am not weak] By compassion.
And I burn not] πυρουμαι, i.e. am exceedingly grieved. Compare Psalms 10:2; Psalms 7:14. He hotly pursueth the poor. The apostle was even scorched and scalded with sorrow and holy indignation, he felt twinges when others were hurt.
