Ezekiel 4:14
12 And you must eat the food as you would a barley cake. You must bake it in front of them over a fire made with dried human excrement.” 13 And the Lord said, “This is how the people of Israel will eat their unclean food among the nations where I will banish them.” 14 And I said, “Ah, Sovereign Lord, I have never been ceremonially defiled before. I have never eaten a carcass or an animal torn by wild beasts; from my youth up, unclean meat has never entered my mouth.” 15 So he said to me, “All right then, I will substitute cow’s manure instead of human excrement. You will cook your food over it.” 16 Then he said to me, “Son of man, I am about to remove the bread supply in Jerusalem. They will eat their bread ration anxiously, and they will drink their water ration in terror
Acts 10:14
12 In it were all kinds of four-footed animals and reptiles of the earth and wild birds. 13 Then a voice said to him, “Get up, Peter; slaughter and eat!” 14 But Peter said, “Certainly not, Lord, for I have never eaten anything defiled and ritually unclean!” 15 The voice spoke to him again, a second time, “What God has made clean, you must not consider ritually unclean!” 16 This happened three times, and immediately the object was taken up into heaven.
Notes and References
"... Peter’s response has confounded many scholars who rationalize how he should have simply selected for consumption a pure animal since all creatures were lying in front of him on the canopy. But Luke is not interested in engaging Peter and the heavens in a battle over semantics. Luke is more eager to move on to the moral of the vision, which really concerns people, rather than delay in portraying Peter trying to outwit a divine mandate that declares (in a vision) all foods to be pure. In this way, Luke chooses to present a Peter who refuses to imply in any way, even in a vision, that he would eat non-kosher animals. This is not the first or last time in Jewish tradition that a human figure will resist a divine mandate to commit an act that presumably involves the transgression of a precept from the Mosaic Torah. The prime example in Ezekiel 4:14 has already been pointed, which might have even inspired the wording of Peter’s reply in Acts 10:14 and 11:8 ..."
