17 The Lord will bring on you and on your people and on your ancestral house such days as have not come since the day that Ephraim departed from Judah-the king of Assyria." 18 On that day the Lord will whistle for the fly that is at the sources of the streams of Egypt, and for the bee that is in the land of Assyria. 19 And they will all come and settle in the steep ravines, and in the clefts of the rocks, and on all the thornbushes, and on all the pastures. 20 On that day the Lord will shave with a razor hired beyond the River-with the king of Assyria-the head and the hair of the feet, and it will take off the beard as well. 21 On that day one will keep alive a young cow and two sheep, 22 and will eat curds because of the abundance of milk that they give; for everyone that is left in the land shall eat curds and honey. 23 On that day every place where there used to be a thousand vines, worth a thousand shekels of silver, will become briers and thorns. 24 With bow and arrows one will go there, for all the land will be briers and thorns; 25 and as for all the hills that used to be hoed with a hoe, you will not go there for fear of briers and thorns; but they will become a place where cattle are let loose and where sheep tread.

Matthew Henry's Commentary on Isaiah 7:17-25

Commentary on Isaiah 7:17-25

(Read Isaiah 7:17-25)

Let those who will not believe the promises of God, expect to hear the alarms of his threatenings; for who can resist or escape his judgments? The Lord shall sweep all away; and whomsoever he employs in any service for him, he will pay. All speaks a sad change of the face of that pleasant land. But what melancholy change is there, which sin will not make with a people? Agriculture would cease. Sorrows of every kind will come upon all who neglect the great salvation. If we remain unfruitful under the means of grace, the Lord will say, Let no fruit grow on thee henceforth for ever.
