Sir 8:19
King James Version
“Open not thine heart to every man, lest he requite thee with a shrewd turn.”
Context
16Strive not with an angry man, and go not with him into a solitary place: for blood is as nothing in his sight, and where there is no help, he will overthrow thee.
17Consult not with a fool; for he cannot keep counsel.
18Do no secret thing before a stranger; for thou knowest not what he will bring forth.
19Open not thine heart to every man, lest he requite thee with a shrewd turn.
