Give ear and hear my voice. Isaiah makes use of a preface, as if he were about to speak of something important and very weighty; for we are not wont to demand attention from our hearers, unless when we are about to say what is very important. And yet he seems here to speak of common and ordinary subjects, as for example, about agriculture, sowing, thrashing, and such like operations. But the Prophet intended to direct the minds of his hearers to higher matters; for when he discourses about the judgments of God, and shews with what wisdom God governs the world, though wicked men think that everything moves by chance and at random, he intended to lay down and explain a difficult subject, in a plain style, by metaphors drawn from objects which are well known and understood. We often complain that God winks too much at the crimes of wicked men, because he does not immediately punish them agreeably to our wish; but the Prophet shews that God appoints nothing but what is just and proper. The design of this preface therefore is, that men may perceive their stupidity in carping at the judgments of God, and putting an unfavourable construction on them, while even in the ordinary course of nature they have a very bright mirror, in which they may see them plainly. There is an implied expostulation with men who shut their eyes amidst so clear light. He shews that they are dull and stupid in not understanding the works of God which are so manifest, and yet are so rash and daring that they presume to judge and censure what is hidden. In like manner Paul also, when speaking of the resurrection, pronounces that those who do not perceive the power of God in the seeds which are thrown into the earth are madmen. "Thou fool, that which thou sowest does not grow or vegetate till it has rotted." (1-Corinthians 15:36.) Thus Isaiah here declares that those who do not see the wisdom of God in things so obvious are stupid, and, in short, that men are blind and dull in beholding the works of God.

Give ye ear - In this verse the prophet introduces an important and striking illustration drawn from the science of agriculture. It is connected with the preceding part of the chapter, and is designed to show the propriety of what the prophet had said by an appeal to what they all observed in the cultivation of their lands. The previous discourse consists mainly of reproofs and of threatenings of punishment on God's people for their profane contempt of the messengers of God. He had threatened to destroy their nation, and so remove them for a time to a distant land. This the prophet had himself said Isaiah 28:21 was his 'strange work.' To vindicate this and to show the propriety "of God's adopting every measure, and of not always pursuing the same course in regard to his people," he draws an illustration from the farmer. He is not always doing the same thing. He adopts different methods to secure a harvest.
He adapts his plans to the soil and to the kind of grain; avails himself of the best methods of preparing the ground, sowing the seed, collecting the harvest, and of separating the grain from the chaff. He does not always plow; nor always sow; nor always thresh. He does not deal with all kinds of land and grain in the same way. Some land he plows in one mode, and some in another; and in like manner, some grain he threshes in one mode, and some in another - adapting his measures to the nature of the soil, and of the grain. Some grain he beats out with a flail; some he bruises; but yet he will be careful not to break the kernel, or destroy it in threshing it. However severe may appear to be his blows, yet his object is not to crush and destroy it Isaiah 28:28, but it is to remove it from the chaff, and to save it. In all this he acts the part of wisdom, for God has taught him what to do Isaiah 28:26, Isaiah 28:29. So, says the prophet, God will not deal with all of his people in the same manner, nor with them always in the same mode. He will vary his measures as a farmer does. When mild and gentle measures will do, he will adopt them. When severe measures are necessary, he will resort to them. His object is not to destroy his people, anymore than the object of the farmer in threshing is to destroy his grain. The general dedicate the propriety of God's engaging in what the prophet calls his 'strange act,' and 'strange work,' in punishing his people. The allegory is one of great beauty, and its pertinency and keeping are maintained throughout; and it furnishes a most important practical lesson in regard to the mode in which God deals with his people.

Give ye ear, and hear my voice "Listen ye, and hear my voice" - The foregoing discourse, consisting of severe reproofs, and threatenings of dreadful judgments impending on the Jews for their vices, and their profane contempt of God's warnings by his messengers, the prophet concludes with an explanation and defense of God's method of dealing with his people in an elegant parable or allegory; in which he employs a variety of images, all taken from the science of agriculture. As the husbandman uses various methods in preparing his land, and adapting it to the several kinds of seeds to be sown, with a due observation of times and seasons; and when he hath gathered in his harvest, employs methods as various in separating the corn from the straw and the chaff by different instruments, according to the nature of the different sorts of grain; so God, with unerring wisdom, and with strict justice, instructs, admonishes, and corrects his people; chastises and punishes them in various ways, as the exigence of the case requires; now more moderately, now more severely; always tempering justice with mercy; in order to reclaim the wicked, to improve the good, and, finally, to separate the one from the other.

Give ye ear, and hear my voice,.... So said the prophet, as the Targum introduces the words; and because what he was about to say was of importance, and delivered in a parabolical manner, and required attention, he makes use of a variety of words to the same purpose, to engage their attention:
hearken, and hear my speech; now about to be made; listen to it, and get the understanding of it.

The husbandman applies to his calling with pains and prudence, in all the works of it according to their nature. Thus the Lord, who has given men this wisdom, is wonderful in counsel, and excellent in his working. As the occasion requires, he threatens, corrects, spares, shows mercy, or executes vengeance. Afflictions are God's threshing instruments, to loosen us from the world, to part between us and our chaff, and to prepare us for use. God will proportion them to our strength; they shall be no heavier than there is need. When his end is answered, the trials and sufferings of his people shall cease; his wheat shall be gathered into the garner, but the chaff shall be burned with unquenchable fire.

Calling attention to the following illustration from husbandry (Psalm 49:1-2). As the husbandman does his different kinds of work, each in its right time and due proportion, so God adapts His measures to the varying exigencies of the several cases: now mercy, now judgments; now punishing sooner, now later (an answer to the scoff that His judgments, being put off so long, would never come at all, Isaiah 5:19); His object being not to destroy His people any more than the farmer's object in threshing is to destroy his crop; this vindicates God's "strange work" (Isaiah 28:21) in punishing His people. Compare the same image, Jeremiah 24:6; Hosea 2:23; Matthew 3:12.

The address of the prophet is here apparently closed. But an essential ingredient is still wanting to the second half, to make it correspond to the first. There is still wanting the fringe of promise coinciding with Isaiah 28:5, Isaiah 28:6. The prophet has not only to alarm the scoffers, that if possible he may pluck some of them out of the fire through fear (Judges 5:23); he has also to comfort believers, who yield themselves as disciples to him and to the word of God (Isaiah 8:16). He does this here in a very peculiar manner. He has several times assumed the tone of the mashal, more especially in chapter 26; but here the consolation is dressed up in a longer parabolical address, which sets forth in figures drawn from husbandry the disciplinary and saving wisdom of God. Isaiah here proves himself a master of the mashal. In the usual tone of a mashal song, he first of all claims the attention of his audience as a teacher of wisdom. V. 23 "Lend me your ear, and hear my voice; attend, and hear my address!" Attention is all the more needful, that the prophet leaves his hearers to interpret and apply the parable themselves. The work of a husbandman is very manifold, as he tills, sows, and plants his field. Vv. 24-26 "Does the ploughman plough continually to sow? to furrow and to harrow his land? Is it not so: when he levels the surface thereof, he scatters black poppy seed, and strews cummin, and puts in wheat in rows, and barley in the appointed piece, and spelt on its border? And He has instructed him how to act rightly: his God teaches it him." The ploughing (chârash) which opens the soil, i.e., turns it up in furrows, and the harrowing (siddēd) which breaks the clods, take place to prepare for the sowing, and therefore not interminably, but only so long as it necessary to prepare the soil to receive the seed. When the seed-furrows have been drawn in the levelled surface of the ground (shivvâh), then the sowing and planting begin; and this also takes place in various ways, according to the different kinds of fruit. Qetsach is the black poppy (nigella sativa, Arab. habbe soda, so called from its black seeds), belonging to the ranunculaceae. Kammōn was the cummin (cuminum cyminum) with larger aromatic seeds, Ar. kammūn, neither of them our common carraway (Kmmel, carum). The wheat he sows carefully in rows (sōrâh, ordo; ad ordinem, as it is translated by Jerome), i.e., he does not scatter it about carelessly, like the other two, but lays the grains carefully in the furrows, because otherwise when they sprang up they would get massed together, and choke one another. Nismân, like sōrâh, is an acc. loci: the barley is sown in a piece of the field specially marked off for it, or specially furnished with signs (sı̄mânı̄m); and kussemeth, the spelt (ζειά, also mentioned by Homer, Od. iv 604, between wheat and barley), along the edge of it, so that spelt forms the rim of the barley field. It is by a divine instinct that the husbandman acts in this manner; for God, who established agriculture at the creation (i.e., Jehovah, not Osiris), has also given men understanding. This is the meaning of v'yisserō lammishpât: and (as we may see from all this) He (his God: the subject is given afterwards in the second clause) has led him (Proverbs 31:1) to the right (this is the rendering adopted by Kimchi, whilst other commentators have been misled by Jeremiah 30:11, and last of all Malbim Luzzatto, "Cosi Dio con giustizia corregge;" he would have done better, however, to say, con moderazione).
