Matthew 15:2 presents the Pharisees' complaint about handwashing that prompted Jesus' teaching on true defilement.

Matthew 23:25 uses the same inside/outside contrast: external ritual purity hides inward greed, directly parallel to the defilement teaching.

Matthew 23:26 continues the cup metaphor: first clean the inside, then outside—reinforcing Jesus' priority of heart purity over ritual.

Matthew 23:28 echoes this same contrast: outward appearance versus inner corruption—the true source of defilement.

Revelation 21:27 states nothing unclean enters the New Jerusalem—directly applying Jesus' definition of what defiles a person.

Revelation 21:8 lists those who inherit the second death—murderers, sexually immoral, etc.—matching the defilement list from Jesus' teaching.

Ephesians 5:3-6 lists sexual immorality and greed as sins excluding from God's kingdom, echoing the heart-borne defilement Jesus taught.

1 Corinthians 6:18-20 calls to flee sexual immorality because the body is a temple, directly applying Jesus' teaching that inner purity—not externals—defiles.

1 Corinthians 6:9-11 lists sins from the heart (sexual immorality, theft, etc.) but adds that believers were washed and sanctified—showing transformation from defilement.

1 Corinthians 3:16 declares believers are God's temple, reinforcing that defilement is internal—not from external washing but heart purity.

Luke 11:38-40 records a similar rebuke at a Pharisee's house: God made both inside and outside, so inner purity matters more.

Mark 7:4 adds other purification traditions like washing from the market, showing the extent of external cleanness rules Jesus counters.

Mark 7:3 explains the Jewish tradition of handwashing, providing background for the controversy Jesus addresses.

Jeremiah 4:14 calls for washing the heart from evil and wicked thoughts—exactly what Jesus teaches defiles a person here.

1 Corinthians 3:17 warns that destroying God's temple brings judgment, connecting to the seriousness of inner defilement that corrupts the temple.

James 1:14 traces sin to internal desires—the same inner source Jesus says defiles a person here.

1 Corinthians 6:13 similarly distinguishes between food (neutral) and bodily sins—aligning with Jesus' point that what goes in doesn't defile.
