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

But you have knowledge that with a feeble body I was preaching the good news to you the first time;

εξευρετε δε οτι προτερον σας εκηρυξα το ευαγγελιον εν ασθενεια της σαρκος,

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