13 Regard not spells and divinations, for that is communion with Satan. Love not idle prating, not even in behalf of righteousness. Discourse concerning yourself begin not, even in behalf of what is becoming. Flee and hide yourself from wrangling, as from a violent robber. See that you be not a surety in a loan, lest you sin. According as you have, assist him, (even) the man that is poorer than you. Mock not the foolish man; pray that you be not even as he. Him that sins blame not, lest you also be put to confusion.
To him that repents of his sins be a helper and counsellor, and encourage him that is able to rise. Let him hold fast hope in God, and his sin shall be burned as stubble. Visit the sick and be not wearied, that you may be beloved of men. Be familiar with the house of mourning, but a stranger to the house of feasting. Be not constant in drinking wine, lest your shortcomings multiply. Cast a wall round your lips, and set a guard upon your mouth; endure suffering with your neighbour and share also in his tribulation. A good friend in tribulation is made known to him that loves him. In charity follow the deceased, with sorrow and with offerings, and pray that he may have rest in the hidden place whither he is going.
