Isaiah 28:24

“Doth the ploughman plough all day to sow? &c.] Or, “every day”; he ploughs in order to sow; by ploughing he prepares the ground for sowing, that is his end in ploughing; and he may plough a whole day together when he is at it, but he does not plough every day in the year; he has other work to do besides ploughing, as is later mentioned; such as breaking of clods, sowing seed, and threshing the grain after it is ripe, and reaped, and gathered. The prophet signifies that the Lord, like a ploughman, had different sorts of work; he was not always doing one and the same thing; and particularly, that he would not be always admonishing and threatening men, and making preparation for his judgments,…”

“all day--emphatic; he is not always ploughing: he also "sows," and that, too, in accordance with sure rules (Isa 28:25). doth he open--supply "always." Is he always harrowing?”

“Doth - The plowman doth not spend all his time in plowing the ground; but he has several times for several works. And so God has his times and seasons for several works, and his providence is various at several times, and towards several people. Therefore those scoffing Israelites were guilty of great folly, in flattering themselves, because of God's long patience towards them; for God will certainly take a time to thresh, and break them with his judgments, as at present he plowed and harrowed them, and so prepared them for it by his threatenings. Open - Understand, all day. Break - Which they used to do with a kind of harrow. Isaiah 28:25”

“28:24-29 A farmer knows that there are right and wrong ways to do things, but the leaders of Judah were not that intelligent.”
