Numbers 20:17Meaning & Commentary from the Church Fathers

In our situation, if anyone strays—whether out of malice or ignorance—this presents a significant danger, both for themselves in succumbing to sin and for leading others astray. Instead, we ought to follow the straight path, remaining vigilant as advised in Proverbs, ensuring we do not veer to the right or left (Proverbs 4:27). Such is the essence of our weaknesses, which creates considerable responsibility for the good shepherd, who must thoroughly understand the souls in his care and guide them in accordance with the principles of righteous and upright shepherding, reflecting the nature of our true Shepherd.

In reference to the instruction, "Let not thou stray to the right hand or to the left" (Deuteronomy 17:11), it is evident that virtue is achieved through effort. Generosity lies at a midpoint between wastefulness and greed; nobility of spirit exists between arrogance and humility; and true piety finds its balance between superstition and unrighteousness. Thus, wise individuals have recognized that vices are the extremes which deviate from virtues, positioning virtues at the center. It seems clear to me that the path to all virtues is a balanced one, reflecting your inquiry about avoiding straying from the true path. Embrace the noble way.
