Galatians 4:13

Through infirmity of the flesh I preached the Gospel unto you. S. Jerome explains this to mean that he gave them the first and weak elements only of the faith, because of their weakness with regard to spiritual things. He also gives as a second interpretation of infirmity of the flesh, Paul's sicknesses and headaches, and as a third, his persecutions, poverty, and sufferings in general, which might make him seem an Apostle, weak, miserable, and despicable, and so unable to gain the respect of the Galatians. Ver. 14. And my temptation which was in my flesh ye despised not. Erasmus takes temptation in the active sense, viz., as though Paul had tempted the Galatians by his unattractive presence and speech. But it is better to take it passively, as being identical with the object of temptation. The meaning then is: You did not despise me in my weakness and my abject condition, which had the effect of making me a temptation to you, but you received me as an angel, nay, as Christ Himself. [Note. The Vulgate is: "And your temptation which was in my flesh."]
