Sirach 13:11

11 Affect not to be made equal unto him in talk, and believe not his many words: for with much communication will he tempt thee, and smiling upon thee will get out thy secrets:

Sirach 13:11 In-Context

9 If thou be invited of a mighty man, withdraw thyself, and so much the more will he invite thee.
10 Press thou not upon him, lest thou be put back; stand not far off, lest thou be forgotten.
11 Affect not to be made equal unto him in talk, and believe not his many words: for with much communication will he tempt thee, and smiling upon thee will get out thy secrets:
12 But cruelly he will lay up thy words, and will not spare to do thee hurt, and to put thee in prison.
13 Observe, and take good heed, for thou walkest in peril of thy overthrowing: when thou hearest these things, awake in thy sleep.
