Sirach 8:18-19

Wycliffe Bible

¹⁸ Make thou not a counsel before a stranger; for thou knowest not, what he shall bring forth.

¹⁹ Make not thine heart known to each man, but only to a very (or to a true) friend, and proved; lest peradventure he bring to thee false grace, that is, feigned friendship, and despise thee. [To all men thine heart open thou not; lest peradventure it bring into thee false grace, and it put reproof to thee.]
