Ben Sira 6:7

7 When you gain a friend, gain him through testing, and do not trust him hastily.

Ben Sira 6:7 In-Context

5 A pleasant voice multiplies friends, and a gracious tongue multiplies courtesies.

6 Let those that are at peace with you be many, but let your advisers be one in a thousand.

7 When you gain a friend, gain him through testing, and do not trust him hastily.

8 For there is a friend who is such at his own convenience, but will not stand by you in your day of trouble.

9 And there is a friend who changes into an enemy, and will disclose a quarrel to your disgrace.
