Matthew Poole and continuators on 2 Corinthians 11:27

27 In weariness and painfulness, in watchings often, in hunger and thirst, in fastings often, in cold and nakedness .

The Apostle reckons up several afflictive Evils, ordinarily incident to such as travel in foreign Countries. Of this nature were the weariness and painfulness, the hunger and thirst, the cold and nakedness here mentioned. He also mentioneth watchings and fastings, as voluntary Acts of Discipline, which he used for the end mentioned, 1 Cor. 9.27. For the keeping under his body, and bringing it in subjection, and that he might the better attend and discharge the work of the Ministry.
