Ambrosiaster — on 2Cor 1:9 (COMMENTARY ON PAUL'S EPISTLES)

“Paul means that there was such a violent upsurge of evil against preachers of the faith that death was staring them in the face. But God does not refuse his protection to people in extreme danger, especially when they belong to him. He rescued them when they were in deep despair. Their affliction was so great that they would not have withstood it if God had not been with them.”
