Therefore, those whom God so joins together [in the marriage bond], no person must ever separate."
1 Corinthians 7:10-14
Now I command married people, although it is [really] the Lord's command [See. Mark 10:2-12]: A wife should not separate from her husband. [Note: This act implies the intention of pursuing a legal and permanent breach of the marriage relationship by divorce. "Separate" and "divorce" appear to be used interchangeably in this section. See verses 11-15].
Ephesians 5:28
In the same way also, husbands should love their own wives as they love their own bodies. The man who loves his own wife [actually] loves himself.
Hebrews 13:4
Marriage should be considered honorable among all people and its sexual responsibilities should be faithfully kept. For God will judge [and condemn] those people who are sexually immoral and who are sexually unfaithful to their mates.
