King James Bible
"Ye know how through infirmity of the flesh I preached the gospel unto you at the first."
Paul reminds the Galatians of his physical weakness or illness when he first came to them. This 'infirmity' likely refers to a specific ailment that detained him in Galatia, though its exact nature remains debated among scholars. Despite his physical condition, Paul fulfilled his mission of proclaiming the gospel during his initial visit. This highlights how God's power works through human weakness, and establishes Paul's sacrificial commitment to the Galatians from the beginning of their relationship.
