Keil & Delitzsch, on Prov 21:7

7 The violence of the godless teareth them away, For they have refused to do what is right. The destruction which they prepare for others teareth or draggeth them away to destruction, by which wicked conduct brings punishment on itself; their own conduct is its own executioner (cf. Pro 1:19); for refusing to practise what is right, they have pronounced judgment against themselves, and fallen under condemnation. Rightly Jerome, detrahent, with Aquila, κατασπάσει = j'gurrem (as Hab 1:15), from גּרר; on the contrary, the lxx incorrectly, ἐπιξενωθήσεται, from גוּר, to dwell, to live as a guest; and the Venet., as Luther, in opposition to the usus loq.: δεδίξεται (fut. of δεδίσσεσθαι, to terrify), from גוּר, to dread, fear, which also remains intrans., with the accus. following, Deu 32:27. The Syr. and the Targ. freely: robbery (Targ. רבּוּנא, perhaps in the sense of usury) will seize them, viz., in the way of punishment. In Arab. jarr (jariyratn) means directly to commit a crime; not, as Schultens explains, admittere crimen paenam trahens, but attrahere (arripere), like (Arab.) jany (jinâytn), contrahere crimen; for there the crime is thought of as violent usurpation, here as wicked accumulation.
