1 Corinthians 7:6

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

1 Corinthians 7:10

7:10 To the married I give this command – not I, but the Lord ¹  – a wife should not divorce a husband

1 Corinthians 7:12

7:12 To the rest I say – I, not the Lord ²  – if a brother has a wife who is not a believer and she is happy to live with him, he should not divorce her.

1 Corinthians 7:40

7:40 But in my opinion, she will be happier if she remains as she is – and I think that I too have the Spirit of God!

[7:10]  ¹ sn Not I, but the Lord. Here and in v. 12 Paul distinguishes between his own apostolic instruction and Jesus’ teaching during his earthly ministry. In vv. 10-11, Paul reports the Lord’s own teaching about divorce (cf. Mark 10:5-12).

[7:12]  ² 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.
