“In Much Talk Thou Shalt Not Escape Sin” (Day 24 of the Holy Rule)
Let us do what the Prophet saith: “I said, I will take heed of my ways, that I sin not with my tongue: I have set a guard to my mouth, I was dumb, and was humbled, and kept silence even from good things.” Here the prophet showeth that, if at times we ought to refrain from useful speech for the sake of silence, how much more ought we to abstain from evil words on account of the punishment due to sin.
