Isaiah 7:20

"In that day will the Lord shave with a razor, the thing for hire on the shore of the river, with the king of Assyria, the head and the hair of the feet; and even the beard it will take away." Knobel takes the hair to be a figurative representation of the produce of the land; but the only thing which at all favours the idea that the flora is ever regarded by biblical writers as the hairy covering of the soil, is the use of the term nâzir as the name of an uncultivated vine left to itself (Lev 25:5). The nation of Judah is regarded here, as in Isa 1:6, as a man stript naked, and not only with all the hair of his head and feet shaved off (raglaim, a euphemism), but what was regarded as the most shameful of all, with the hair of his beard shaved off as well. To this end the Almighty would make use of a razor, which is more distinctly defined as hired on the shore of the Euphrates (Conductitia in litoribus Euphratis: nâhâr stands here for hannâhâr), and still more precisely as the king of Asshur (the latter is again pronounced a gloss by Knobel and others). "The thing for hire:" hassecı̄râh might be an abstract term (hiring, Conductio), but it may also be the feminine of sâcı̄r, which indicates an emphatic advance from the indefinite to the more definite; in the sense of "with a razor, namely, that which was standing ready to be hired in the lands on both sides of the Euphrates, the king of Assyria." In hassecı̄râh (the thing for hire) there was involved the bitterest sarcasm for Ahaz. The sharp knife, which it had hired for the deliverance of Judah, was hired by the Lord, to shave Judah most thoroughly, and in the most disgraceful manner. Thus shaved, Judah would be a depopulated and desert land, in which men would no longer live by growing corn and vines, or by tr…

This chapter is an occasional sermon, in which the prophet sings both of mercy and judgment to those that did not perceive or understand either; he piped unto them, but they danced not, mourned unto them, but they wept not. Here is, I. The consternation that Ahaz was in upon an attempt of the confederate forces of Syria and Israel against Jerusalem (Isa 7:1, Isa 7:2). II. The assurance which God, by the prophet, sent him for his encouragement, that the attempt should be defeated and Jerusalem should be preserved (Isa 7:3-9). III. The confirmation of this by a sign which God gave to Ahaz, when he refused to ask one, referring to Christ, and our redemption by him (Isa 7:10-16). IV. A threatening of the great desolation that God would bring upon Ahaz and his kingdom by the Assyrians, notwithstanding their escape from this present storm, because they went on still in their wickedness (Isa 7:17-25). And this is written both for our comfort and for our admonition.

7:20 shave off everything: your land, your crops, and your people: In the ancient Near East, forced shaving was an act of disgrace (see 2 Sam 10:4-5). Here it was a metaphor for the despoiling of the country.
