What defiles a man and the DNA Code? This study will look at 13 actions the Lord says defiles a person. How do these actions relate to the numbers 21, 13, and 23, the number for seed from a father. But first, let us refresh what the numbers 13 and 21 mean. The number 21 is defined in the King James Bible as exceeding sinfulness of sin. We have studied in the past that the number 13 is the number defined for depravity and rebellion. In verse 21, there are 13 descriptions of what defiles a man.(Mark 7:17-23) "And when he was entered into the house from the people, his disciples asked him concerning the parable. {18} And he saith unto them, Are ye so without understanding also? Do ye not perceive, that whatsoever thing from without entereth into the man, it cannot defile him; {19} Because it entereth not into his heart, but into the belly, and goeth out into the draught, purging all meats? {20} And he said, That which cometh out of the man, that defileth the man. {21} For from within, out of the heart of men, proceed (1)evil thoughts, (2)adulteries, (3)fornications, (4)murders, {22} (5)Thefts, (6)covetousness, (7)wickedness, (8)deceit, (9)lasciviousness, (10)an evil eye, (11)blasphemy, (12)pride, (13)foolishness: {23} All these evil things come from within, and defile the man."
