Jakesie60 is not far off. There are many things in the Old Testament that, with the arrival, crucifixion and resurrection of Jesus, become irrelevant, and are expressly addressed in the New Testament. This is one of them. People like to quote the Old Testament, out of context, assuming that this instruction applies to us as it did to men thousands of years ago. It doesn't. It's glib to do so.
Mark 7:14-23: "And he (Jesus) called the people to him again and said to them, “Hear me, all of you, and understand: 15 There is nothing outside a person that by going into him can defile him, but the things that come out of a person are what defile him.” 17 And when he had entered the house and left the people, his disciples asked him about the parable. 18 And he said to them, “Then are you also without understanding? Do you not see that whatever goes into a person from outside cannot defile him, 19 since it enters not his heart but his stomach, and is expelled?” (Thus he declared all foods clean.) 20 And he said, “What comes out of a person is what defiles him. 21 For from within, out of the heart of man, come evil thoughts, sexual immorality, theft, murder, adultery, 22 coveting, wickedness, deceit, sensuality, envy, slander, pride, foolishness. 23 All these evil things come from within, and they defile a person.”
