Ben Sira 32:19

19 Do nothing without advice; and when thou hast once done, repent not.

Ben Sira 32:19 In-Context

17 A sinful man will not be reproved, but findeth an excuse according to his will.

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 on a level way.
