Sirach 13:9–13
9 When an influential person invites you, be reserved,
and he will invite you more insistently.
10 Do not be forward, or you may be rebuffed;
do not stand aloof, or you will be forgotten.
11 Do not try to treat him as an equal,
or trust his lengthy conversations;
for he will test you by prolonged talk,
and while he smiles he will be examining you.
12 Cruel are those who do not keep your secrets;
they will not spare you harm or imprisonment.
13 Be on your guard and very careful,
for you are walking about with your own downfall.c
