In Matthew 5:31, Jesus cites the OT law allowing a certificate of divorce — the very law he overturns here with his stricter teaching.

Matthew 5:32 parallels this saying but adds an exception for sexual immorality — showing the same core teaching with a clarifying clause.

Matthew 19:9 records the same divorce saying in a parallel account — also with the exception clause not present in Mark.

Luke 16:18 gives an identical saying on divorce and remarriage — confirming the same dominical teaching.

Romans 7:3 teaches that remarriage while a spouse lives is adultery — directly echoing Jesus’s principle here about the binding nature of marriage.

1 Corinthians 7:10 cites the Lord’s command that a wife should not separate — a direct reference to Jesus’s teaching in this very passage.

1 Corinthians 7:11 adds that if separated, she must remain unmarried or reconcile — building on Jesus’s prohibition of divorce here.

In Exodus 20:14, the commandment against adultery is the basis Jesus uses to declare that divorce and remarriage constitutes adultery.

In Deuteronomy 24:2, the Mosaic law permitted divorce with a certificate; Jesus here overturns that permission by declaring remarriage adultery.
