'In That Day': Assyrian Devastation and the Desolation of the Land
18It will happen in that day that Yahweh will whistle for the fly that is in the uttermost part of the rivers of Egypt, and for the bee that is in the land of Assyria.19They shall come, and shall all rest in the desolate valleys, in the clefts of the rocks, on all thorn hedges, and on all pastures.20In that day the Lord will shave with a razor that is hired in the parts beyond the River, even with the king of Assyria, the head and the hair of the feet; and it shall also consume the beard.21It shall happen in that day that a man shall keep alive a young cow, and two sheep.22It shall happen, that because of the abundance of milk which they shall give he shall eat butter, for everyone will eat butter and honey that is left within the land.23It will happen in that day that every place where there were a thousand vines worth a thousand silver shekels, 35 ounces, so 1000 shekels is about 10 kilograms or 22 pounds. will be for briers and thorns.24People will go there with arrows and with bow, because all the land will be briers and thorns.25All the hills that were cultivated with the hoe, you shall not come there for fear of briers and thorns; but it shall be for the sending out of oxen, and for sheep to tread on.”
God commands empires like a beekeeper whistles for his swarm—absolute sovereignty over history's most powerful forces, leaving no refuge from judgment except in radical dependence on him alone.
In five vivid oracles each introduced by "in that day," Isaiah depicts Yahweh summoning the armies of Egypt and Assyria like a beekeeper whistling for his swarms, shaving Judah bare as a sign of humiliation, and reducing the once-prosperous land to a wilderness of briars and thorns. Yet threading through the ruin is an unexpected mercy: a remnant survives, sustained on butter and honey — the primal food of the promised land — even amid the desolation. Judgment and grace are paradoxically intertwined: the same catastrophe that strips the land bare also strips away every false security, leaving God alone as the source of life.
Verse 18 — The Divine Whistle and the Summoned Swarms The image of Yahweh whistling (Hebrew: šāraq) for flies and bees is startling in its domesticity. A beekeeper controlled his hive with a whistle or hiss; Isaiah applies this humble image to the sovereign Lord of history, who commands the vast imperial armies of Egypt (the fly, associated with the Nile delta, cf. Ps 78:45) and Assyria (the bee, whose ferocity was proverbial in the ancient Near East) with the same ease. The "uttermost part of the rivers of Egypt" points to the Nile tributaries — Egypt's military heartland. The nations are not autonomous agents of chaos; they are instruments entirely under divine command. This verse belongs to the Syro-Ephraimite crisis context (ca. 734–732 BC), when King Ahaz of Judah sought Assyrian aid against the coalition of Israel and Aram, thereby setting in motion forces he could not control. Isaiah's oracle warns that Ahaz's political maneuvering will not protect Judah; on the contrary, it will bring these very armies onto Judean soil.
Verse 19 — Occupation of Every Corner The swarming locust-like occupation is total: "desolate valleys," "clefts of the rocks," "thorn hedges," "all pastures." Nothing is exempt. The Hebrew nəḥālîm (wadis) and the nəqîqê hasselaʿîm (fissures of the rocks) together suggest a land turned inside out — every refuge, natural or cultivated, colonized by foreign power. This is the land promised to Abraham now overrun, a reversal of the Exodus conquest.
Verse 20 — The Hired Razor and the Shame of Shaving The image shifts to razor and barber. The Lord will use the king of Assyria as a "hired razor" — the word śəkîrâ (hired) is deliberately ironic: Ahaz paid Assyria to come (2 Kgs 16:7–8), so Assyria is literally a hired tool, but Yahweh is the one doing the hiring at the deepest level of history. Shaving the head, feet (a Hebrew euphemism for the pubic region), and beard was a profound act of degradation in the ancient Near East; it signified captivity, mourning, and the utter erasure of honorable identity (cf. 2 Sam 10:4–5; Job 1:20). All three zones of the body — crown, sexual vitality, face — are stripped. This is total humiliation, the symbolic inverse of priestly consecration (Lev 21:5 forbade priests from shaving as a mark of their holy dignity). Judah will be treated not as God's priestly nation but as a conquered slave.
Verses 21–22 — Survival on Butter and Honey The scene contracts dramatically: not the armies of nations, but a single man with one heifer and two sheep. The abundance of milk (producing , curds or clarified butter, and , honey) is not luxury but the bare minimum of survival in a depopulated land. Paradoxically, the phrase "butter and honey" appeared in 7:15 as the food the Immanuel child would eat — the food of the land at its most elemental. Here it signals both reduction (the agricultural economy has collapsed) and preservation (life continues in the remnant). Where vineyards and grain fields once sustained thousands, now a handful of animals sustains one man. Yet he . This is the dialectic of Isaianic theology: the judgment that destroys is also the judgment that purifies and preserves a remnant.
Catholic tradition reads this passage on several levels simultaneously, following the fourfold sense of Scripture outlined by St. John Cassian and enshrined in the Catechism (CCC §115–119).
Literally and historically, the oracle was fulfilled with terrible precision in the Assyrian campaigns of Tiglath-Pileser III and Sennacherib, who depopulated the northern territories and besieged Jerusalem. St. Jerome, who lived near these lands and wrote his Commentary on Isaiah with detailed geographical knowledge, emphasized the literal accuracy of Isaiah's agricultural imagery, noting that the terraced vineyards of Judah were indeed abandoned for centuries after the Babylonian deportations.
Allegorically, the Church Fathers saw the "hired razor" as a type of the devil permitted by God to chastise — but never destroy — his people. St. Augustine in The City of God (Book XVIII) reflects on how God uses pagan empires as scourges for his people's purification, never ceding ultimate sovereignty. The razor hired by Ahaz — that is, by human pride and faithless political calculation — becomes an instrument of divine pedagogy.
The remnant sustained by butter and honey carries deep typological resonance. The Catechism teaches that the Old Testament figures are "fulfilled" in Christ (CCC §128–130). The man with one cow and two sheep who eats butter and honey in the desolated land prefigures the remnant Israel from which the Messiah springs — the anawim, the poor of Yahweh, stripped of every worldly security but nourished by God alone. Pope Benedict XVI in Jesus of Nazareth traces this "remnant theology" as the very matrix from which the New Testament community of disciples is born.
The briars and thorns of verses 23–25 carry unavoidable Edenic resonance (Gen 3:18): the curse upon the ground returns in full force upon the covenant land. The land mirrors the spiritual condition of the people. Catholic moral theology, following Aquinas (ST I-II, q. 87), understands temporal suffering as medicinal punishment — not mere retribution, but the loving discipline of a Father who refuses to let his children rest comfortably in their infidelity.
This passage confronts the contemporary Catholic with a searching question: in what have I placed my security? Ahaz's fatal error was not simply political naivety but a theological one — he trusted in an imperial alliance rather than in the word of God just delivered through Isaiah (7:4: "Be calm and fear not"). The Catholic today faces analogous temptations: to seek security in financial stability, cultural respectability, political alliances, or institutional prestige rather than in God alone.
The image of the man surviving on butter and honey amid universal ruin speaks directly to the spirituality of detachment taught by St. John of the Cross: when everything extraneous is stripped away, what remains is sufficient, and more than sufficient. The remnant does not merely survive — he eats. God provides at the most elemental level.
Practically, this passage invites an examination of conscience around what we have built up that may need to be stripped away — habits of comfort, attachments to status, reliance on systems rather than on prayer. It also calls the Church as a whole to embrace a "remnant spirituality" — smaller, poorer, more dependent on God — rather than to mourn the passing of cultural Christendom as if the Church's vitality depended on civilizational dominance. The briars may be growing where the vineyards once were. But the butter and honey remain.
Verses 23–25 — Vineyards Become Wilderness The economic devastation is measured in the most precise terms: a thousand vines worth a thousand silver shekels — prime viticultural property — will yield only briars and thorns. The vineyard, Israel's classic symbol of covenantal privilege (cf. Isa 5:1–7), has become wasteland. Arrows and bow replace the vintner's knife and the farmer's hoe. The cultivated hill terraces of Judah — one of the great agricultural achievements of Iron Age Palestine — will revert to pasture for oxen and sheep. There is a grim regression here from culture to nature, from covenant life to bare existence. Yet even in this, oxen still tread and sheep still graze: the land is not dead, only stripped of its excess, awaiting renewal.
