1 Corinthians 7:6

But I speak this by permission, and not of commandment.

Cross-reference

1 Corinthians 7:12 shows Paul again distinguishing his words from a direct command of the Lord — directly parallel to the concession here.

1 Corinthians 7:25 repeats the formula: no command from the Lord, only Paul's judgment — identical to this concession.

2 Corinthians 8:8 similarly says 'not as a command' but as proof of love — the same disclaimer Paul uses here about marital concessions.

Matthew 19:8 explains Moses' divorce permission as a concession — the same concept of divine concession Paul applies here.

2 Corinthians 11:17 distinguishes Paul's speech from the Lord's — a similar qualifier about his own authority, though in a boastful context.
