Sirach 6: 5-17

5
A kind mouth multiplies friends, and gracious lips prompt friendly greetings.
6
Let your acquaintances be many, but one in a thousand your confidant.
7
When you gain a friend, first test him, and be not too ready to trust him
8
For one sort of friend is a friend when it suits him, but he will not be with you in time of distress.
9
Another is a friend who becomes an enemy, and tells of the quarrel to your shame.
10
Another is a friend, a boon companion, who will not be with you when sorrow comes.
11
When things go well, he is your other self, and lords it over your servants;
12
But if you are brought low, he turns against you and avoids meeting you.
13
Keep away from your enemies; be on your guard with your friends.
14
A faithful friend is a sturdy shelter; he who finds one finds a treasure.
15
A faithful friend is beyond price, no sum can balance his worth.
16
A faithful friend is a life-saving remedy, such as he who fears God finds;
17
For he who fears God behaves accordingly, and his friend will be like himself.
