(4) The heart also of the rash . . .--"Heart," as in Proverbs 4:23 and elsewhere, for the intellect rather than the emotions. The "rash" are those that are "hurried," precipitate, reckless; the "stammerers," those who have no power to speak clearly of the things of God, who hesitate and are undecided.

Verse 4. - The heart also of the rash; i.e. of those who were rash and hasty, who would not give themselves time to understand the warnings addressed to them, or to think of the real character of their actions. These shall, in Messiah's kingdom, "have the gift of discernment to perceive things in their true nature" (Delitzsch). The tongue of the stammerers. The tongue of those who hitherto have spoken hesitatingly and inconsistently on moral and religions subjects shall be ready - i.e., prompt and eager - to speak upon them with clearness and elegance. The grace given to the uneducated fishermen of Galilee enabled them to preach and teach gospel truth, not only with clearness, but with refinement.

32:1-8 Christ our righteous King, and his true disciples, are evidently here intended. The consolations and graces of his Spirit are as rivers of water in this dry land; and as the overhanging rock affords refreshing shade and shelter to the weary traveller in the desert, so his power, truth, and love, yield the believer the only real protection and refreshment in the weary land through which he journeys to heaven. Christ bore the storm himself, to keep it off from us. To him let the trembling sinner flee for refuge; for he alone can protect and refresh us in every trial. See what pains sinners take in sin; they labour at it, their hearts are intent upon it, and with art they work iniquity; but this is our comfort, that they can do no more mischief than God permits. Let us seek to have our hearts more freed from selfishness. The liberal soul devises liberal things concerning God, and desires that He will grant wisdom and prudence, the comforts of his presence, the influence of his Spirit, and in due time the enjoyment of his glory.The heart also of the rash shall understand knowledge,.... Such who have been hasty and precipitant, as the word (c) signifies; who have not given themselves time to consider what they have read or heard, or has been proposed unto them, and have hastily received every thing that has been suggested to them, especially by carnal sense and reason, shall now sit down, and coolly consider things, and so gain an understanding of divine and spiritual knowledge, of the knowledge of Christ, of his person, offices, grace, righteousness, and salvation; an experimental knowledge and understanding of these things, heart and not head knowledge:

and the tongue of the stammerer shall be ready to speak plainly; or, "shall make haste to speak neatly" (d); elegantly and politely; such who hesitated in their speech, and spoke in a blundering manner, and scarcely intelligibly, especially when they spoke of divine and spiritual things, yet now, without the least hesitation, in the freest and most ready manner, with all plainness and propriety shall talk of these things, to the great delight, satisfaction, and use of those that hear them: this was true of the apostles of Christ, those babes and sucklings, out of whose mouth God ordained praise, and who were most of them Galilaeans, very illiterate and unpolished, and yet these, especially when they had the gift of tongues, spake the great things of God very readily, and in good language; and also is true of other ministers of the word, raised up among the barbarous nations of the world.
