‏ 1 Corinthians 9:2

2. yet doubtless--yet at least I am such to you.

seal of mine apostleship--Your conversion by my preaching, accompanied with miracles ("the signs of an apostle," Ro 15:18, 19; 2Co 12:12), and your gifts conferred by me (1Co 1:7), vouch for the reality of my apostleship, just as a seal set to a document attests its genuineness (Joh 3:33; Ro 4:11).
