1 Corinthians 7:6

7:6 I say this as a concession, not as a command.

1 Corinthians 7:12

7:12 To the rest I say – I, not the Lord ¹  – if a brother has a wife who is not a believer and she is happy to live with him, he should not divorce her.

[7:12]  ¹ sn I, not the Lord. Here and in v. 10 Paul distinguishes between his own apostolic instruction and Jesus’ teaching during his earthly ministry. In vv. 12-16, Paul deals with a situation about which the Lord gave no instruction in his earthly ministry.
