Thieves... robbers. The former are ordinary thieves who pilfer secretly; the latter are robbers who act with violence, or members of a marauding expedition. How art thou cut off! An interposed ejaculation of the prophet, sympathizing with the Edomites for the utter desolation which he sees in vision.
Septuagint, ποῦ ἄν ἀπεῤῥίφης; "Where wouldst thou have been east away?" taking a different reading; Vulgate, Quomodo conticuisses? "How wouldst thou have been silent?" i.e. for fear. Till they had enough.
Would they not have taken such plunder as they wanted, and then decamped? The grape gatherers would leave some bunches untouched, which escaped their notice. There is no reference to the charitable law in Le 19:10; Deuteronomy 24:21, which would not affect, or be known unto, these grape plunderers.
