Sirach 32:20

20 Go not in a way wherein thou mayest fall, and stumble not among the stones.

Sirach 32:20 In-Context

18 A man of counsel will be considerate; but a strange and proud man is not daunted with fear, even when of himself he hath done without counsel.
19 Do nothing without advice; and when thou hast once done, repent not.
20 Go not in a way wherein thou mayest fall, and stumble not among the stones.
21 Be not confident in a plain way.
22 And beware of thine own children.
