Mark Chapter 7, Verse 19
From BibleWiki
19: οτι ουκ εισπορευεται αυτου εις την καρδιαν αλλ εις την κοιλιαν και εις τον αφεδρωνα εκπορευεται καθαριζον παντα τα βρωματα
19: Because it entereth not into his heart, but into the belly,
and goeth out into the draught, purging all meats?
19: Because it entereth not into his heart but goeth into his belly
and goeth out into the privy, purging all meats?
Entereth not into his heart. Does not reach or affect the mind, the soul, and consequently cannot pollute it. Even if it should affect the body, yet it cannot the soul, and consequently cannot need to be cleansed by a religious ordinance. The notions of the Pharisees, therefore, are not founded in reason, but are mere superstition.
The draught. The sink, the vault.
Purging all meats, The word purging, here, means to purify, to cleanse. What is thrown out of the body is the innutrious part of the food taken into the stomach, and leaving only that which is proper for the support of life; and it cannot, therefore, defile the soul.
All meats. All food; all that is taken into the body to support life. The meaning is, that the economy or process by which life is supported, purifies or renders nutritious all kinds of food. The unwholesome parts are separated, and the wholesome only are taken into the system. This agrees with all that has since been discovered of the process of digestion, and of the support of life. The food taken into the stomach is, by the gastric juice, converted into a thick pulp, called chyme. The nutritious part of this is conveyed into small vessels and changed into a milky substance called chyle. This is changed into blood, and the blood conveys nutriment and support to all parts of the system. The useless parts of the food are thrown off.
