Proverbs 4:23

with all diligence--or, "above," or "more than all," custody (compare Margin), all that is kept (compare Eze 38:7), because the heart is the depository of all wisdom and the source of whatever affects life and character (Mat 12:35; Mat 15:19).

Keep thy heart with all diligence,.... The mind from vanity, the understanding from error, the will from perverseness, the conscience clear of guilt, the affections from being inordinate and set on evil objects, the thoughts from being employed on bad subjects; and the whole from falling into the hands of the enemy, or being the possession of Satan: great diligence had need be used in keeping it, since it is naturally so deceitful and treacherous; a strict eye is to be kept upon it; all the avenues to it to be watched, that nothing hurtful enters, or evil comes out; it is to be kept by all manner of means that can be thought of, by prayer, hearing, reading, meditation; and, above all, by applying to Christ for his grace and Spirit to sanctify, preserve, and keep it. Or, "above all keeping, keep thine heart" (b); though other things are to be kept, and care taken of them, as kingdoms and cities, and towns and families, and treasures and riches; yet the heart above all: for out of it are the issues of life; of natural life: it is the seat of it, from whence all actions of life are derived; it is, as philosophers say, the first that lives, and the last that dies; and it is the seat of spiritual life the principle of it is formed in it; from whence all spiritual and vital actions flow, and which lead unto and issue in eternal life: as is a man's heart, such is his state now, and will be hereafter; if the heart is quickened and sanctified by the grace of God, the man will live a life of faith and holiness here, and enjoy everlasting life hereafter: and if the heart is right, so will the actions of men be; they are regulated and denominated by it; they will then spring from right principles, and be directed to right ends, and performed with right views; great care therefore s…

After this general preface the exhortation now becomes special: 23 Above all other things that are to be guarded, keep thy heart, For out from it life has its issues. 24 Put away from thee perverseness of mouth, And waywardness of lips put far from thee. 25 Thine eyes should look straight forward, And thine eyelids look straight to the end before thee. 26 Make even the path of thy feet, And let all thy ways be correct. 27 Turn not aside to the right and to the left; Remove thy foot from evil. Although משׁמר in itself and in this connection may mean the object to be watchfully avoided (cavendi) (vid., under Pro 2:20): thus the usage of the language lying before us applies it, yet only as denoting the place of watching or the object observandi; so that it is not to be thus explained, with Raschi and others: before all from which one has to protect himself (ab omni re cavenda), guard thine heart; but: before all that one has to guard (prae omni re custodienda), guard it as the most precious of possessions committed to thy trust. The heart, which according to its etymon denotes that which is substantial (Kernhafte) in man (cf. Arab. lubb, the kernel of the nut or almond), comes here into view not as the physical, but as the intellectual, and specially the ethical centrum. Pro 4:24 The תּוצאות are the point of a thing, e.g., of a boundary, from which it goes forth, and the linear course proceeding from thence. If thus the author says that the תּוצאות חיּים go out from the heart, (Note: The correct form here is כּי־ממּנּוּ, with the Makkeph to כי.) he therewith implies that the life has not only its fountain in the heart, but also that the direction which it takes is determined by the heart. Physically considered, the heart is the receptacle for the blood, in which the soul l…

When the things of God are to be taught precept must be upon precept, and line upon line, not only because the things themselves are of great worth and weight, but because men's minds, at the best, are unapt to admit them and commonly prejudiced against them; and therefore Solomon, in this chapter, with a great variety of expression and a pleasant powerful flood of divine eloquence, inculcates the same things that he had pressed upon us in the foregoing chapters. Here is, I. An earnest exhortation to the study of wisdom, that is, of true religion and godliness, borrowed from the good instructions which his father gave him, and enforced with many considerable arguments (Pro 4:1-13). II. A necessary caution against bad company and all fellowship with the unfruitful works of darkness (Pro 4:14-19). III. Particular directions for the attaining and preserving of wisdom, and bringing forth the fruits of it (Pro 4:20-27). So plainly, so pressingly, is the case laid before us, that we shall be for ever inexcusable if we perish in our folly.

4:23 In the Old Testament, the heart represents the center of emotions, thinking, and reasoning (e.g., Gen 6:5; Deut 4:29; Ps 131:1). The heart is crucial in the battle between wisdom and foolishness, between righteousness and evil (see Matt 5:8; 13:15; John 12:40; Rom 6:17).
