Sirach 4:26

26 Be not ashamed to confess thy sins; and force not the course of the river.

Sirach 4:26 In-Context

24 For by speech wisdom shall be known: and learning by the word of the tongue.
25 In no wise speak against the truth; but be abashed of the error of thine ignorance.
26 Be not ashamed to confess thy sins; and force not the course of the river.
27 Make not thyself an underling to a foolish man; neither accept the person of the mighty.
28 Strive for the truth unto death, and the Lord shall fight for thee.
