Jerome : (Verse 20.) Your sons are cast out, they have slept at the head of all the streets, like a trapped wild goat: full of the indignation of the Lord, the rebuke of your God. LXX: Your sons are destitute and sleeping at the head of all the streets: like a half-cooked beet, full of the fury of the Lord, and lacking from the Lord your God. As for the half-cooked beet, the remaining interpreters translated it as a captured and trapped wild goat, which is called 'Tho' in Hebrew, a type of wild animal found in the wilderness, listed among the clean animals in Leviticus and Deuteronomy. The Syriac language they have translated as thoreth, which means beta. Let us pass over the name and consider the meaning of it. Your sons, like wild oxen caught in snares, have slept in the streets and public squares, placing their naked bodies on the bare ground, thereby revealing the wrath of the Lord and the rebuke of their God, indicating their own misery. Furthermore, according to the Seventy: those who do not desire spiritual riches in every word, knowledge, and good work, but choose to be poor and not endure the threat, will by no means dwell in the houses that are built with virtues, but will remain at the beginning of the roads and at the exit, touching everything and leaving everything behind. Those who are said to sleep well in that sleep, of which it is written: They have slept their sleep and found nothing (Ps. 75:6). In that sleep, the Assyrian king has put them to sleep. And they are compared to half-cooked beets, which are a type of vegetable that is very cheap and fragile. About these vegetables, I believe that it is said in the Psalms: Do not be jealous of evildoers, nor envy those who do iniquity. For like grass, they will quickly wither, and like the green vegetables, they will quickly fall (Ps. 36:1, 2). For it is the food of the sick. He who is once unbelieving is called raw beetroot. But he who is content with simple faith, without reason and the truth of doctrines, performs the works of justice, can be called cooked beetroot. Furthermore, he who fluctuates between vices and virtues, and approaches the service of God with a double heart, is most rightly called half-cooked beetroot, of whom God speaks in the Apocalypse of John: Would that you were either hot or cold: but because you are lukewarm, I will vomit you out (Rev. III, 15, 16). Those who are lukewarm and sleeping are full of the fury of the Lord, and they are loose, or failing, through the Lord God. Not that the Lord is the cause of their loosening, who did not make death, nor does he take pleasure in the destruction of the living. But rather, those who have sinned in the Law, let them be judged by the Law, which works the wrath of God against those who are transgressors of it. — Commentary on Isaiah Theodoret of Cyrus : By the slumber, he has indicated their indolence, and by the cooked vegetables their laxness. But what he adds is even harsher than what he has said before: "They that are full of the anger of the Lord are caused to faint by the Lord God." By their iniquity they draw my anger, and by reason of my anger, they are deprived of my kind attention and despoiled of every kind of strength. — COMMENTARY ON Isaiah 16:51.20
