1 Corinthians 7:10-14

Goodspeed(i) 10 To those already married my instructions are—and they are not mine, but the Lord's—that a wife is not to separate from her husband. 11 If she does separate, she must remain single or else become reconciled to him. And a husband must not divorce his wife. 12 To other people I would say, though not as Christ's command, if a Christian has a wife who is not a believer, and she is willing to live with him, he must not divorce her, 13 and a woman who has a husband who is not a believer, but is willing to live with her, must not divorce her husband. 14 For the husband who is not a believer is consecrated through union with his wife, and the woman who is not a believer is consecrated through union with her Christian husband, for otherwise your children would be unblessed, but, as it is, they are consecrated.
