Приповісті 27:1

In the group Pro 27:1-6 of this chapter every two proverbs form a pair. The first pair is directed against unseemly boasting: 1 Boast not thyself of to-morrow, For thou knowest not what a day bringeth forth. The ב of בּיום is like, e.g., that in Pro 25:14, the ב of the ground of boasting. One boasts of to-morrow when he boasts of that which he will then do and experience. This boasting is foolish and presumptuous (Luk 12:20), for the future is God's; not a moment of the future is in our own power, we know not what a day, this present day or to-morrow (Jam 4:13), will bring forth, i.e., (cf. Zep 2:2) will disclose, and cannot therefore order anything beforehand regarding it. Instead of לא־תדע (with Kametz and Mugrash), אל־תדע (thus e.g., the Cod. Jaman) is to be written; the Masora knows nothing of that pausal form. And instead of מה־יּלד יום, we write מה יּלד יום with Zinnorith. יּלד before יום has the tone thrown back on the penult., and consequently a shortened ult.; the Masora reckons this word among the twenty-five words with only one Tsere.

Here is, 1. A good caution against presuming upon time to come: Boast not thyself, no, not of tomorrow, much less of many days or years to come. This does not forbid preparing for tomorrow, but presuming upon tomorrow. We must not promise ourselves the continuance of our lives and comforts till tomorrow, but speak of it with submission to the will of God and as those who with good reason are kept at uncertainty about it. We must not take thought for the morrow (Mat 6:34), but we must cast our care concerning it upon God. See Jam 4:13-15. We must not put off the great work of conversion, that one thing needful, till tomorrow, as if we were sure of it, but today, while it is called today, hear God's voice. 2. A good consideration, upon which this caution is grounded: We know not what a day may bring forth, what event may be in the teeming womb, of time; it is a secret till it is born, Ecc 11:5. A little time may produce considerable changes, and such as we little think of. We know not what the present day may bring forth; the evening must commend it. Nescis quid serus vesper vehat - Thou knowest not what the close of evening may bring with it. God has wisely kept us in the dark concerning future events, and reserved to himself the knowledge of them, as a flower of the crown, that he may train us up in a dependence upon himself and a continued readiness for every event, Act 1:7.

27:1 We should plan (24:27), but our plans succeed only when God so wills (16:1, 3, 33; Jas 4:13-16). Only fools think that they control the future.
