In Matthew 5:32, Jesus adds an exception for sexual immorality not present here — a contrasting version of the same divorce teaching.

In Matthew 19:9, Jesus similarly includes the exception clause for sexual immorality, differing from the absolute statement here.

In Mark 10:11, the same absolute prohibition of divorce and remarriage as adultery is recorded — a parallel account.

In Mark 10:12, the teaching is expanded to a woman divorcing her husband — a complementary case not mentioned here.

In 1 Corinthians 7:10-12, Paul cites the Lord's command against divorce (same as here) and applies it to mixed marriages.

In Deuteronomy 24:1, divorce with a certificate was permitted — a law Jesus intentionally tightens here by forbidding remarriage as adultery.

Malachi 2:16 shows God's hatred of divorce, providing the OT foundation for Jesus' strict teaching here on marriage and remarriage.
