Matthew 25:33

His right hand.. the left] These expressions have the same significance in most languages. In Plato's 'Republic' Er the Pamphylian is allowed to see the judgment after death executed by the judges of the underworld. The judges sit between two gaps, one leading to heaven, the other to hell. 'After passing sentence, the judges commanded the just to take the road to the right upwards through the heaven, and fastened in front of them some symbol of the judgment which had been given; while the unjust were ordered to take the road downward to the left, and also carried behind them evidence of all their evil deeds.' Similarly the rabbis said, 'Those on the right hand are the just, who study the Law, which is at the right hand of God (Deuteronomy 33:2); those on the left are the wicked, who study riches (Proverbs 3:16).' 'In those on the right hand righteousness, in those on the left hand guilt, preponderates.'
