Proverbs 20:25

25 It is a snare to a man to cry out hastily "holy;" And first after vows to investigate. Two other interpretations of the first line have been proposed. The snare of a man devours, i.e., destroys the holy; but then מוקשׁ אדם must be an expression of an action, instead of an expression of an endurance, which is impossible. The same is true against the explanation: the snare of a man devours, i.e., consumes, eats up the holy, which as such is withdrawn from common use. Jerome with his devotare sanctos, and Luther with his das Heilige lestern [to calumniate the holy], give to לוּע = בּלע a meaning which loses itself in the arbitrary. Accordingly, nothing is to be done with the meaning καταπίεται (Aquila, the Venet.). But ילע will be the abbreviated fut. of לוּע (from ילוּע), or לעע (ילע), Job 6:3 = (Arab.) laghâ temere loqui (proloqui); and קדשׁ (after Hitzig: consecration, which is contrary to usage) is like κορβᾶν, Mar 7:11, the exclamation to which one suddenly gives utterance, thereby meaning that this or that among his possessions henceforth no longer belongs to him, but is consecrated to God, and thus ought to be delivered up to the temple. Such a sudden vow and halting deference to the oath that has been uttered is a snare to a man, for he comes to know that he has injured himself by the alienation of his property, which he has vowed beyond that which was due from him, or that the fulfilling of his vow is connected with difficulties, and perhaps also to others, with regard to whom its disposal was not permitted to him, is of evil consequences, or it may be he is overcome by repentance and is constrained to break his oath. The lxx hits the true meaning of the proverb with rare success: Παγὶς ἀνδρὶ ταχύ τι τῶν ἰδίων ἁγιάσαι, μετὰ δὲ τὸ εὔξασθαι μεταν…

Two things, by which God is greatly affronted, men are here said to be ensnared by, and entangled not only in guilt, but in trouble and ruin at length: - 1. Sacrilege, men's alienating holy things and converting them to their own use, which is here called devouring them. What is devoted in any way to the service and honour of God, for the support of religion and divine worship or the relief of the poor, ought to be conscientiously preserved to the purposes designed; and those that directly or indirectly embezzle it, or defeat the purpose for which it was given, will have a great deal to answer for. Will a man rob God in tithes and offerings? Mal 3:8. Those that hurry over religious offices (their praying and preaching) and huddle them up in haste, as being impatient to get done, may be said to devour that which is holy. 2. Covenant-breaking. It is a snare to a man, after he has made vows to God, to enquire how he may evade them or get dispensed with, and to contrive excuses for the violating of them. If the matter of them was doubtful, and the expressions were ambiguous, that was his fault; he should have made them with more caution and consideration, for it will involve his conscience (if it be tender) in great perplexities, if he be to enquire concerning them afterwards (Ecc 5:6); for, when we have opened our mouth to the Lord, it is too late to think of going back, Act 5:4.

20:25 Counting the cost is particularly important when making a promise to God (see Judg 11:29-40; Eccl 5:4-6).
