I know you not - You were not in the company of those who attended me to the marriage-feast, and are unknown to me. Applied to professing Christians, having only a profession of religion, but no real piety, it means, I do not know or acknowledge you as Christians. I do not approve of you, or delight in you, or admit that you are my friends. The word “know” is often used in the sense of approving, loving, acknowledging as real friends and followers. See Matthew 7:23; Psa 1:6; 2 Timothy 2:19; 1 Thessalonians 5:12.
