I lead in the way (better, I walk in the way) of righteousness. I act always according to the rules of justice. In the midst of the paths of judgment. I swerve not to one side or the other (Proverbs 4:27).
So the psalmist prays, "Teach me, O Lord, the way of thy statutes; and I shall keep it unto the end;" "Cause me to know the way wherein I should walk" (Psalms 119:33; Psalms 143:8). And the promise is given to the faithful in Isaiah 30:21, "Thine ears shall hear a word behind thee, saying, This is the way, walk ye in it, when ye turn to the right hand, and when ye turn to the left."
Virtue, as Aristotle has taught us, is the mean between two extremes.
