Do not allow your speech to cause you to sin, and do not say before the messenger (priest) of God that it was a mistake. Why should God be angry because of your voice (words) and destroy the work of your hands?

Do not say, “Why were the old days better than these?”
For it is not from wisdom that you ask about this.

Do not be excessively righteous [like those given to self-conceit], and do not be overly wise (pretentious)—why should you bring yourself to ruin?

Do not be excessively or willfully wicked and do not be a fool. Why should you die before your time?
