Learn to do well; seek judgment, relieve the oppressed, judge the fatherless, plead for the widow. Relieve the oppressed "Amend that which is corrupted" - אשרו חמוץ asheru chamots. In rendering this obscure phrase I follow Bochart, (Hieroz. Part i., lib. ii., cap. 7), though I am not perfectly satisfied with this explication of it.
