Read Mark 7:19 Using Other Translations
Because it entereth not into his heart, but into the belly, and goeth out into the draught, purging all meats?
since it enters not his heart but his stomach, and is expelled?" (Thus he declared all foods clean.)
Food doesn’t go into your heart, but only passes through the stomach and then goes into the sewer.” (By saying this, he declared that every kind of food is acceptable in God’s eyes.)
