(19) It entereth not into his heart.--The words are not in St. Matthew, and emphasise the contrast with what follows. The "heart" is, after the common Hebrew idiom, the symbol of the mind as well as the affections. (Comp. Proverbs 7:7; Proverbs 9:4; Proverbs 9:16; Proverbs 10:13, in all of which "understanding" stands for the Hebrew of "heart.")

Purging all meats.--This also is peculiar to St. Mark, and presents some difficulties. In the commonly received text, the participle is in the neuter nominative, agreeing with the nominative to the verb "goeth out." But in this construction it is difficult to see in what sense that which goeth into the mouth--itself an article of food, with no special character--can be said to purge or cleanse all other forms of food. The better MSS., however, give the participle in the masculine. This has been explained by many as a grammatical anomaly, and the participle being treated as if it agreed (though in a different case) with the word "draught" or "cesspool," the latter is said to cleanse all meats, as removing the excreta, or impure parts, from them, and leaving only that which nourishes the body. A far better construction, both as to grammar and meaning, is found by making the word "purging," or better, cleansing, agree with the subject of the verb "He saith," in Mark 7:18--"He saith this . . . and in so saying, cleanseth all meats." So taken, the words anticipate, in almost the same terms, the truth of Acts 10:15, "What God hath cleansed, that call not thou common." The construction is tenable grammatically, has the support of high authority both ancient and modern, and obviously gives a much better sense. It is a possible conjecture that the words "cleansing all meats" may have been, at first, a marginal note (like the addition in Mark 7:16), attached to "He saith," and have afterwards found their way into the text.

7:14-23 Our wicked thoughts and affections, words and actions, defile us, and these only. As a corrupt fountain sends forth corrupt streams, so does a corrupt heart send forth corrupt reasonings, corrupt appetites and passions, and all the wicked words and actions that come from them. A spiritual understanding of the law of God, and a sense of the evil of sin, will cause a man to seek for the grace of the Holy Spirit, to keep down the evil thoughts and affections that work within.Because it entereth not into his heart,.... Which is the seat and fountain of all moral pollution; and if that is not defiled, no other part can be; and that that is not defiled by eating and drinking, unless in case of intemperance, is clear; because food and drink do not go into it:

but into the belly; it is taken in at the mouth, goes down the throat, and is received into the stomach, and from thence it passes through the bowels:

and goeth into the draught; , "the private house", as the Jews call it, without going into the heart at all:

purging all meats; that which it leaves behind, is pure and nourishing; and whatever is gross and impure, is carried with it into the draught, so that nothing remains in the man that is defiling.
