Leviticus 11:1-17 lists the unclean animals Peter is referring to — the dietary law he has always observed and now must reconsider.

Leviticus 20:25 commands distinguishing clean from unclean — the very principle behind Peter's refusal to eat what God now declares clean.

In Ezekiel 4:14, the prophet protests he has never eaten unclean food — a direct parallel to Peter's own objection to God's command.

Leviticus 11:2 lists the dietary laws Peter is citing — the very distinction between clean and unclean animals he refuses to eat.

Daniel 1:8 shows Daniel refusing defilement from royal food — strong parallel to Peter's initial refusal before the vision.

Matthew 15:11 records Jesus teaching that food does not defile — directly countering Peter's refusal and foreshadowing his lesson.

Mark 7:15 records Jesus teaching that nothing outside defiles a person — the very principle Peter struggles to accept when told to eat unclean food.

Romans 14:14 states nothing is unclean in itself, echoing the lesson Peter must learn — that ceremonial food laws no longer apply.

In Matthew 16:22, Peter similarly rebukes Jesus' prophecy of death — both show Peter resisting God's plan out of devotion.

Ezekiel 44:31 restricts priests from eating unclean meat — a related dietary law though specific to priests, not all Israel.

Hebrews 13:9 warns against being carried away by teachings about ceremonial foods — this connects to Peter's dietary scruple as part of that same issue.
