John Wesley on Deuteronomy 32:36

For - Or, nevertheless, having spoken of the dreadful calamity which would come upon his people, he now turns his discourse into a more comfortable strain, and begins to shew that after God had sorely chastised his people, he would have mercy upon them and turn their captivity. Judge his people - Shall plead their cause, shall protect and deliver them. Repent - Of the evils he hath brought upon them. None shut up - Either in their strong cities or castles or other hiding places, or in the enemies hands or prisons, whence there might be some hope or possibility of redemption; and none left, as the poor and contemptible people are neglected and usually left by the conquerors in the conquered land, but all seem to be cut off and destroyed.
