1 Corinthians 6:13 directly parallels Jesus' point: 'Food for the stomach and the stomach for food, but God will destroy both' — both affirm food's temporary nature.

Colossians 2:22 calls such rules 'things that perish with use' — echoing Jesus' point that food is eliminated and doesn't defile.

Mark 7:18 is the synoptic parallel, nearly verbatim, reinforcing Jesus' teaching that external things don't defile.

Mark 7:19 continues the same teaching, adding that Jesus declared all foods clean — directly expanding the digestive point.

Colossians 2:21 quotes ascetic rules ('Do not handle, taste, touch') — the very kind of dietary regulations Jesus refutes here.

James 3:6 teaches that the tongue defiles the whole body — consistent with Jesus' later point that defilement comes from within, not from food.
