Sirach 6

Fall not into the grip of desire, lest, like fire, it consume your strength; Your leaves it will eat, your fruits destroy, and you will be left a dry tree, For contumacious desire destroys its owner and makes him the sport of his enemies.

A kind mouth multiplies friends, and gracious lips prompt friendly greetings. Let your acquaintances be many, but one in a thousand your confidant. When you gain a friend, first test him, and be not too ready to trust him. For one sort of friend is a friend when it suits him, but he will not be with you in time of distress.

Another is a friend who becomes an enemy, and tells of the quarrel to your shame. Another is a friend, a boon companion, who will not be with you when sorrow comes. When things go well, he is your other self, and lords it over your servants; but if you are brought low, he turns against you and avoids meeting you.

Keep away from your enemies; be on your guard with your friends. A faithful friend is a sturdy shelter; he who finds one finds a treasure. A faithful friend is beyond price, no sum can balance his worth. A faithful friend is a life-saving remedy, such as he who fears God finds; For he who fears God behaves accordingly, and his friend will be like himself.

From your youth embrace discipline; thus will you find wisdom with graying hair. As though plowing and sowing, draw close to her; then await her bountiful crops. For in cultivating her you will labor but little, and soon you will eat of her fruits.

How irksome she is to the unruly! The fool cannot abide her. She will be like a burdensome stone to test him, and he will not delay in casting her aside. For discipline is like her name, she is not accessible to many.

If you are willing to listen, you will learn; if you give heed, you will be wise. Frequent the company of the elders; whoever is wise, stay close to him. Be eager to hear every godly discourse; let no wise saying escape you.

If you see a man of prudence, seek him out; let your feet wear away his doorstep! Reflect on the precepts of the LORD, let his commandments be your constant meditation; then he will enlighten your mind, and the wisdom you desire he will grant.
