Oh you mean Genesis where it’s clear clean and unclean is already established?
Let me walk you through this,
God came in the flesh as a perfect human, Yeshua. Spotless, to take our place in punishment, death.
That means He never sinned before He was crucified, not once.
Therefore, He never ate swine before He was crucified, not once.
So are you trying to tell me after Yeshua raised from the dead, He started sinning?
What you half quoted in Matthew, is just talking about what it says, eating with unwashed hands. It never says anything about different unclean foods.
