This also hath proceeded from Jehovah of hosts. This passage is explained by some, as if The Prophet had said that the science of agriculture proceeded from the Lord; but I consider it to be the application of what goes before. Having pointed out the wisdom of God, even in the smallest matters, he bids us, in like manner, raise our eyes to higher subjects, that we may learn to behold with greater reverence his wonderful and hidden judgments. A passing observation on the 26th verse may be made, and indeed ought to be made, that not only agriculture, but likewise all the arts which contribute to the advantage of mankind, are the gifts of God, and that all that belongs to skillful invention has been imparted by him to the minds of men. Men have no right to be proud on this account, or to arrogate to themselves the praise of invention, as we see that the ancients did, who, out of their ingratitude to God, ranked in the number of the gods those whom they considered to be the authors of any ingenious contrivance. Hence arose deification and that prodigious multitude of gods which the heathens framed in their own fancy. Hence arose the great Ceres, and Triptolemus, and Mercury, and innumerable others, celebrated by human tongues and by human writings. The Prophet shews that such arts ought to be ascribed to God, from whom they have been received, who alone is the inventor and teacher of them. If we ought to form such an opinion about agriculture and mechanical arts, what shall we think of the learned and exalted sciences, such as Medicine, Jurisprudence, Astronomy, Geometry, Logic, and such like? Shall we not much more consider them to have proceeded from God? Shall we not in them also behold and acknowledge his goodness, that his praise and glory may be celebrated both in the smallest and in the greatest affairs?

This also cometh - That is, these various devices for threshing his grain comes from the Lord no less than the skill with which he tills his land. (see Isaiah 28:26).
And excellent in working - Or rather, who magnifies (חגדיל chigdiyl) his wisdom ( תוּשׁיה tûshı̂yâh). This word properly means wisdom, or understanding Job 11:6; Job 12:16; Job 26:3; Proverbs 3:21; Proverbs 8:14; Proverbs 18:1. The idea of the prophet is, that God, who had so wisely taught the farmer, and who had instructed him to use such various methods in his husbandry, would also be himself wise, and would pursue similar methods with his people. He would not always pursue the same unvarying course, but would vary his dispensations as they should need, and as would best secure their holiness and happiness. We see:
1. The reason of afflictions. It is for the same cause which induces the farmer to employ various methods on his farm.
2. We are not to expect the same unvarying course in God's dealings with us. It would be as unreasonable as to expect that the farmer would be always plowing, or always threshing.
3. We are not to expect always the same kind of afflictions. The farmer uses different machines and modes of threshing, and adapts them to the nature of the grain. So God uses different modes, and adapts them to the nature, character, and disposition of his people. One man requires one mode of discipline, and another another. At one time we need one mode of correction to call us from sin and temptation; at another another. We may lay it down as a general rule, that "the divine judgments are usually in the line of our offences;" and by the nature of the judgment we may usually ascertain the nature of the sin. If a man's besetting sin is "pride," the judgment will usually be something that is suited to humble his pride; if it be covetousness, his property may be removed, or it may be made a curse; if it be undue attachment to children or friends, they may be removed.
4. God will not crush or destroy his people. The farmer does not crush or destroy his grain. In all the various methods which he uses, he takes care not to pursue it too far, and not to injure the grain. So with God's dealings with his people. His object is not to destroy them, but it is to separate the chaff from the wheat; and he will afflict them only so much as may be necessary to accomplish this. He will not be always bruising his people, but will in due time remit his strokes - just as the thresher does.
5. We should, therefore, bear afflictions and chastisements with patience. God deals with us in mercy - and the design of all his dispensations toward us in prosperity and adversity; in sickness and in health; in success and in disappointment, is to produce the richest and most abundant fruits of righteousness, and to prepare us to enter into his kingdom above.

This also cometh from the Lord of hosts,.... All this wisdom the husbandman has, in manuring his ground, in sowing it with proper seed, and in threshing it out in a manner suitable to it. Agriculture or husbandry, even among the Heathens, is always ascribed to God, as an invention of his, and it was the first work which God put man to, and instructed him in, Genesis 3:23 and as this, so all other arts, and sciences, and manufactures, come from God, even all things in nature, providence, and grace, and the knowledge of them; wherefore he himself must be infinitely wise and knowing; see Psalm 94:9 and be as he is next described:
which is wonderful in counsel: in giving counsel to man, both with respect to things temporal and spiritual; and whose counsel is always wise and good, and for the best; and, when taken, infallibly succeeds. See an instance of his wonderful counsel, Revelation 3:18 and also he is "wonderful" in forming wise plans and schemes of operation; the wise plan of his works of creation and providence was formed in his vast and infinite mind from eternity; the wise scheme of our redemption and salvation by Christ was concerted by him, wherein he has abounded towards us in all wisdom and prudence; and the manner, means, time, and place, of his gathering and the effectual calling of his people, are all wisely fixed by him; and he does all things after "the counsel of his will", Ephesians 1:11 and therefore it follows:
and excellent in working; both as to the matter or things wrought by him, which are the most excellent things in nature, providence, and grace, wrought out either by the Father, or the Son, or the Holy Spirit; and as to manner of working, all being done well and wisely; and likewise with respect to the end, his own glory, and the good of his people.

This also--The skill wherewith the husbandman duly adjusts his modes of threshing is given by God, as well as the skill (Isaiah 28:26) wherewith he tills and sows (Isaiah 28:24-25). Therefore He must also be able to adapt His modes of treatment to the several moral needs of His creatures. His object in sending tribulation (derived from the Latin tribulum, a "threshing instrument," Luke 22:31; Romans 5:3) is to sever the moral chaff from the wheat, not to crush utterly; "His judgments are usually in the line of our offenses; by the nature of the judgments we may usually ascertain the nature of the sin" [BARNES].
This chapter opens the series of prophecies as to the invasion of Judea under Sennacherib, and its deliverance.

This also - This part of the husbandman's discretion. These words contain the application of the similitude. The husbandman manages his affairs with common discretion; but God governs the world, and his church, with wonderful wisdom: he is great and marvellous, both in the contrivance of things, and in the execution of them.
