As you know, it was because of an illness1 that I first preached the gospel to you.
References for Galatians 4:13
Even though my illness was a trial to you, you did not treat me with contempt or scorn. Instead, you welcomed me as if I were an angel of God, as if I were Christ Jesus himself.2
References for Galatians 4:14
What has happened to all your joy? I can testify that, if you could have done so, you would have torn out your eyes and given them to me.
