13. That we must not curse.

In Exodus: "Thou shalt not curse nor speak ill of the ruler of thy people." Also in the thirty-third Psalm: "Who is the man who desires life, and loveth to see good days? Restrain thy tongue from evil, and thy lips that they speak no guile." Of this same thing in Leviticus: "And the Lord spoke to Moses, saying, Bring forth him who hath cursed abroad outside the camp; and all who heard him shall place their hands upon his head, and all the assembly of the children of Israel shall stone him." Of this same thing in Paul's Epistle to the Ephesians: "Let no evil discourse proceed out of your mouth, but that which is good for the edification of faith, that it may give grace to the hearers." Of this same thing to the Romans: "Blessing, and not cursing." Of this same thing in the Gospel according to Matthew: "He who shall say to his brother, Thou fool! shall be liable to the Gehenna of fire." Of this same matter, according to the same Matthew: "But I say unto you, That every idle word which men shall speak, they shall give account for it in the day of judgment. For by thy words thou shalt be justified, and by thy words thou shalt be condemned."
