This parable, which (like many of our Saviour's parables) is borrowed from the husbandman's calling, is ushered in with a solemn preface demanding attention, He that has ears to hear, let him hear, hear and understand, Isa 28:23.

I.The parable here is plain enough, that the husbandman applies himself to the business of his calling with a great deal of pains and prudence, secundum artem - according to rule, and, as his judgment directs him, observes a method and order in his work. 1. In his ploughing and sowing: Does the ploughman plough all day to sow? Yes, he does, and he ploughs in hope and sows in hope, Co1 9:10. Does he open and break the clods? Yes, he does, that the land may be fit to receive the seed. And when he has thus made plain the face thereof does he not sow his seed, seed suitable to the soil? For the husbandman knows what grain is fit for clayey ground and what for sandy ground, and, accordingly, he sows each in its place - wheat in the principal place (so the margin reads it), for it is the principal grain, and was a staple commodity of Canaan (Eze 27:17), and barley in the appointed place. The wisdom and goodness of the God of nature are to be observed in this, that, to oblige his creatures with a grateful variety of productions, he has suited to them an agreeable variety of earths. 2. In his threshing, Isa 28:27, Isa 28:28. This also he proportions to the grain that is to be threshed out. The fitches and the cummin, being easily got out of their husk or ear, are only threshed with a staff and a rod; but the bread-corn requires more force, and therefore that must be bruised with a threshing instrument, a sledge shod with iron, that was drawn to and fro over it, to beat out the corn; and yet he will not be ever threshing it, nor any longer than is necessary to loosen the corn from the chaff; he will not break it, or crush it, into the ground with the wheel of his cart, nor bruise it to pieces with his horsemen; the grinding of it is reserved for another operation. Observe, by the way, what pains are to be taken, not only for the earning, but for the preparing of our necessary food; and yet, after all, it is meat that perishes. Shall we then grudge to labour much more for the meat which endures to everlasting life? Bread-corn is bruised. Christ was so; it pleased the Lord to bruise him, that he might be the bread of life to us.

II.The interpretation of the parable is not so plain. Most interpreters make it a further answer to those who set the judgments of God at defiance: "Let them know that as the husbandman will not be always ploughing, but will at length sow his seed, so God will not be always threatening, but will at length execute his threatenings and bring upon sinners the judgments they have deserved; but in wisdom, and in proportion to their strength, not that they may be ruined, but that they may be reformed and brought to repentance by them." But I think we may give this parable a greater latitude in the exposition of it. 1. In general, that God who gives the husbandman this wisdom is, doubtless, himself infinitely wise. It is God that instructs the husbandman to discretion, as his God, Isa 28:26. Husbandmen have need of discretion wherewith to order their affairs, and ought not undertake that business unless they do in some measure understand it; and they should by observation and experience endeavour to improve themselves in the knowledge of it. Since the king himself is served of the field, the advancing of the art of husbandry is a common service to mankind more than the cultivating of most other arts. The skill of the husbandman is from God, as every good and perfect gift is. This takes off somewhat of the weight and terror of the sentence passed on man for sin, that when God, in execution of it, sent man to till the ground, he taught him how to do it most to his advantage, otherwise, in the greatness of his folly, he might have been for ever tilling the sand of the sea, labouring to no purpose. It is he that gives men capacity for this business, an inclination to it, and a delight in it; and if some were not by Providence cut out for it, and mad to rejoice (as Issachar, that tribe of husbandmen) in their tents, notwithstanding the toil and fatigue of this business, we should soon want the supports of life. If some are more discreet and judicious in managing these or any other affairs than others are, God must be acknowledged in it; and to him husbandmen must seek for direction in their business, for they, above other men, have an immediate dependence upon the divine Providence. As to the other instance of the husbandman's conduct in threshing his corn, it is said, This also comes forth from the Lord of hosts, Isa 28:29. Even the plainest dictate of sense and reason must be acknowledged to come forth from the Lord of hosts. And, if it is from him that men do things wisely and discreetly, we must needs acknowledge him to be wise in counsel and excellent in working. God's working is according to his will; he never acts against his own mind, as men often do, and there is a counsel in his whole will: he is therefore excellent in working, because he is wonderful in counsel. 2. God's church is his husbandry, 1 Co. 3. 9 If Christ is the true vine, his Father is the husbandman (Joh 15:1), and he is continually by his word and ordinances cultivating it. Does the ploughman plough all day, and break the clods of his ground, that it may receive the seed, and does not God by his ministers break up the fallow ground? Does not the ploughman, when the ground is fitted for the seed, cast in the seed in its proper soil? He does so, and so the great God sows his word by the hand of his ministers (Mat 13:19), who are to divide the word of truth and give every one his portion. Whatever the soil of the heart is, there is some seed or other in the word proper for it. And, as the word of God, so the rod of God is thus wisely made use of. Afflictions are God's threshing-instruments, designed to loosen us from the world, to separate between us and our chaff, and to prepare us for use. And, as to these, God will make use of them as there is occasion; but he will proportion them to our strength; they shall be no heavier than there is need. If the rod and the staff will answer the end, he will not make use of his cart-wheel and his horsemen. And where these are necessary, as for the bruising of the bread-corn (which will not otherwise be got clean from the straw), yet he will not be ever threshing it, will not always chide, but his anger shall endure but for a moment; nor will he crush under his feet the prisoners of the earth. And herein we must acknowledge him wonderful in counsel and excellent in working.

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, Gen 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 Psa 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, Rev 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", Eph 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 (Isa 28:26) wherewith he tills and sows (Isa 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," Luk 22:31; Rom 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].
