Sirach 20:20

20 A wise sentence shall be rejected when it cometh out of a fool's mouth; for he will not speak it in due season.

Sirach 20:20 In-Context

18 To slip upon a pavement is better than to slip with the tongue: so the fall of the wicked shall come speedily.

19 An unseasonable tale will always be in the mouth of the unwise.

20 A wise sentence shall be rejected when it cometh out of a fool's mouth; for he will not speak it in due season.

21 There is that is hindered from sinning through want: and when he taketh rest, he shall not be troubled.

22 There is that destroyeth his own soul through bashfulness, and by accepting of persons overthroweth himself.
