Galatians 4:13

Ye know how through infirmity of the flesh I preached the gospel unto you at the first.

but you know that because of weakness of the flesh I preached the Gospel to you the first time.

but ye know that because of an infirmity of the flesh I preached the gospel unto you the first time:

and ye have known that through infirmity of the flesh I did proclaim good news to you at the first,

You know that it was because of an illness that I first preached the gospel to you.
