Mark 10:2 records Jesus' teaching on divorce, which Paul echoes here by forbidding separation and remarriage.

Genesis 2:24 establishes the one-flesh union, the creation basis for Paul's instruction that marriage should not be broken.

Deuteronomy 24:1 permits divorce for indecency, directly opposing Paul's command not to separate.

Matthew 5:32 gives Jesus' exception for sexual immorality; Paul's stricter 'no separation' aligns with this higher standard.

Matthew 19:9 repeats Jesus' divorce teaching with the adultery clause, reinforcing Paul's stance against remarriage after separation.

Mark 10:11 states that divorce and remarriage is adultery, supporting Paul's directive to remain unmarried after separation.

Jeremiah 3:1 uses marriage-divorce imagery for Israel's unfaithfulness, yet God calls them to return — parallels the reconciliation option Paul offers.
