'Humbled' in the Bible

Did I commit a sin when I humbled myself by proclaiming to you the gospel of God free of charge, so that you could be exalted?

and that upon re-visiting you I may be humbled by my God in your presence, and may have to mourn over many whose hearts still cling to their old sins, and who have not repented of the impurity, fornication, and gross sensuality, of which they have been guilty.
