1 Corinthians 9:13 states the same principle: those serving at the altar share in its offerings, just as Israel partakes here.

In Leviticus 7:11-17, the peace offering law shows that eating the sacrifice means participation with the altar, directly supporting Paul's point.

Romans 9:3-8 distinguishes physical Israel from spiritual Israel, directly clarifying that not all fleshly descendants are true Israel.

2 Corinthians 11:18-22 boasts of Paul's own physical Israelite credentials, the same 'Israel after the flesh' referenced here.

Galatians 6:16 invokes the 'Israel of God' as a spiritual group, contrasting the physical Israel partaking in sacrifices here.

Acts 15:29 commands abstaining from food offered to idols, directly supporting Paul's warning against idolatrous participation.

Revelation 2:14 condemns eating things sacrificed to idols — the same practice Paul warns against here, showing its lasting danger.

Revelation 2:20 also condemns eating sacrificed food, linking it to the teaching of Jezebel, amplifying Paul's warning about idolatrous fellowship.

Ephesians 2:11 reminds Gentiles they were once outside physical Israel, the very group Paul's example highlights.
