11 Does the poor man cry at your door? Arise and open for him gladly: refresh him when he is wearied; sustain his heart, for it is sad. You know by experience the affliction of poverty: receive not others in your house, and drive not out the beggar. Have you also a law, a comely law for your household. Establish an order that is wise, that the abjects laugh not at you. Be careful in all your doings, that you be not a sport for fools; be upright and prudent, and both simple and wise. Let your body be quiet and cheerful, your greeting seemly and simple; your discourse without fault, your speech brief and savoury; your words few and sound, full of savour and understanding.
Speak not overmuch, not even words that are wise; for all things that are over many, though they be wise are wearisome.— To them of your household be as a father. Amongst your brethren esteem yourself least, and inferior among your fellows, and of little account with all men. With your friend keep a secret; to those that love you be true. See that there be no wrangling; the secrets of your friends reveal not, lest all that hear you hate you and esteem you a mischiefmaker. With those that hate you wrangle not, neither face to face nor yet in your heart.
No enemy shall you have but Satan his very self. Give counsel to the wife you have wedded; give heed to her doings; as stronger you are answerable that you should sustain her weakness. For weak is womankind, and very ready to fall. Be as a hawk, when kindled (to anger), but when wrath departs from you, be gladsome and also firm, in the blending of diverse qualities. Keep silence among the aged; to the elders give due honour. Honour the priests with diligence, as good stewards of the household. Give due honour to their degree, and search not out their doings. In his degree the priest is an angel, but in his doings a man. By mercy he is made a mediator, between God and mankind.
