According to the sentence of the law which they shall teach you, and according to the judgment which they shall tell you, you shall do: you shall not decline from the sentence which they shall show you, to the right hand, nor to the left.
All Commentaries on Deuteronomy 17:11 Go To Deuteronomy 17
Augustine of Hippo
AD 430
Just as a person has to pick his way between fire and water so as to be neither burned nor drowned, so we should steer our way between the pinnacle of pride and the whirlpool of sloth, as it is written, “turning neither to the right nor to the left.” For there are some who, through fear of being carried up to the heights on the right, slip and are drowned on the left. Others … fear to be sucked in by the soft ease of sloth on the left and are ruined and destroyed by the ostentation of boasting on the other side, and [they] vanish into smoke and ashes.
