John 8:4

They say unto him, Master, this woman was taken in adultery, in the very act.

Cross-reference

Leviticus 20:10 commands death for both adulterer and adulteress — highlighting that only the woman is brought, not the man.

Deuteronomy 22:22 also prescribes death for both parties in adultery — reinforcing the law the Pharisees claim to uphold.

Matthew 1:19 shows Joseph's merciful response to suspected adultery — a contrast to the Pharisees' public accusation here.
