Contradiction with Matthew 15:11
This verse contradicts Exodus 12:19 by emphasizing that what goes into someone's mouth does not defile them, thus downplaying dietary laws.
Matthew 15:11: Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.
Contradiction with Mark 7:18-19
Jesus declares all foods clean, in contrast to the strict regulations seen in Exodus 12:19 about consuming leavened bread.
Mark 7:18-19: Because it entereth not into his heart, but into the belly, and goeth out into the draught, purging all meats?
Contradiction with Romans 14:14
Paul states that nothing is unclean in itself, differing from the strict prohibition of leavened bread found in Exodus 12:19.
Romans 14:14: I know, and am persuaded by the Lord Jesus, that [there is] nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him [it is] unclean. [unclean: Gr. common]
Contradiction with Colossians 2:16-17
Paul suggests not to let anyone judge you by what you eat, contradicting the detailed dietary observances commanded in Exodus 12:19.
Colossians 2:16-17: Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath [days]: [in meat...: or, for eating and drinking] [respect: or, part]
Paradox #1
Exodus 12:19 may pose a contradiction for those who note that it requires complete removal of leaven from homes during the Feast of Unleavened Bread, yet other parts of the Bible don't emphasize such strict behavior for other festivals or times. This could be seen as inconsistent in terms of religious observance standards across the different festivals.
