1 Corinthians 9:1-2

The Rights of an Apostle

9:1 Am I not free? Am I not an apostle? Have I not seen Jesus our Lord? Are you not my work in the Lord? 9:2 If I am not an apostle to others, at least I am to you, for you are the confirming sign ¹  of my apostleship in the Lord.

[9:2]  ¹ tn Grk “the seal.”
