10. Arise ye, and depart--not an exhortation to the children of God to depart out of an ungodly world, as it is often applied; though that sentiment is a scriptural one. This world is doubtless not our "rest," being "polluted" with sin: it is our passage, not our portion; our aim, not our home (2Co 6:17; Heb 13:14). The imperatives express the certainty of the future event predicted. "Since such are your doings (compare Mic 2:7, 8, &c.), My sentence on you is irrevocable (Mic 2:4, 5), however distasteful to you (Mic 2:6); ye who have cast out others from their homes and possessions (Mic 2:2, 8, 9) must arise, depart, and be cast out of your own (Mic 2:4, 5): for this is not your rest" (Nu 10:33; De 12:9; Ps 95:11). Canaan was designed to be a rest to them after their wilderness fatigues. But it is to be so no longer. Thus God refutes the people's self-confidence, as if God were bound to them inseparably. The promise (Ps 132:14) is quite consistent with temporary withdrawal of God from Israel for their sins.
      it shall destroy you--The land shall spew you out, because of the defilements wherewith ye "polluted" it (Le 18:25, 28; Jer 3:2; Eze 36:12-14).
