Contradiction with Proverbs 23:6
This verse advises against eating bread of someone with an evil eye, contrasting with Zechariah 9:7, where unclean things are removed and he is reconciled to God.
Proverbs 23:6: Eat thou not the bread of [him that hath] an evil eye, neither desire thou his dainty meats:
Contradiction with Acts 10:15
This verse, stating nothing God cleans is common or unclean, contradicts the notion in Zechariah 9:7 of unclean things being removed from the mouth.
Acts 10:15: And the voice [spake] unto him again the second time, What God hath cleansed, [that] call not thou common.
Contradiction with Mark 7:19
This verse explains all foods are clean, which conflicts with the idea in Zechariah 9:7 of certain things needing removal from being unclean.
Mark 7:19: And he said, That which cometh out of the man, that defileth the man.
Contradiction with Romans 14:14
Paul's declaration that nothing is unclean in itself contradicts the implication in Zechariah 9:7 that some things are initially unclean.
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]
Paradox #1
The contradiction or conflict in the verse could be seen in the way it addresses the transformation of former enemies or outsiders into part of the community of believers. Some might view this as inconsistent with other parts of scripture that emphasize separation or judgment of outsiders. This could raise questions about the balance between inclusion and exclusivity.
