Ben Sira - chapter 9

9: 1 - 18 (translated by Edgar Goodspeed)
Do not be jealous about the wife of your bosom, and do not teach her an evil lesson, to your own hurt. Do not give your soul to a woman, so that she will trample on your strength. Do not meet a prostitute, or you may fall into her snares. Do not associate with a woman singer, or you may be caught by her wiles. Do not look closely at a virgin, or you may be entrapped in penalties on her account. Do not give yourself to prostitutes, so that you may not lose your inheritance. Do not look around in the streets of the city, and do not wander about the unfrequented parts of it. Avert your eyes from a beautiful woman, and do not look clsely at beauty that belongs to someone else. Many have been led astray by a woman's beauty, and love is kindled by it like a fire. Do not ever sit at table with a married woman, and do not feast and drink with her, or your heart may turn away to her, and you may slip into spiritual ruin.
Do not forsake old friends, for new ones are not equal to them. A new friend is new wine; when it grows old, you will enjoy drinking it. Do not envy the glory of a sinner; for you do not know what disaster awaits him. Do not share in the satisfaction of ungodly men, remember that until death they will not be found upright. Keep far from those who hve the power of life and death. If you do approach them, do not offend them, so that they may not take away your life. Understand that you are striding along among traps, and walking on the city battlements. As far as you can, aim to know your neighbors, and take counsel with those who are wise. Let your discussion be with intelligent people and all your discourse about the Law of the Most High. Let the righteous be your companions at table, and let your exultation be in the fear of the Lord. It is for the skill of the artisan that a piece of work is commended, and a ruler of the poeple is proved wise by his words. The loud of mouth are dreaded in their city, and the one who is rash in speech is hated.
