Sirach 26:11

11 Watch over an impudent eye: and marvel not if she trespass against thee.

Sirach 26:11 In-Context

9 The whoredom of a woman may be known in her haughty looks and eyelids.
10 If thy daughter be shameless, keep her in straitly, lest she abuse herself through overmuch liberty.
11 Watch over an impudent eye: and marvel not if she trespass against thee.
12 She will open her mouth, as a thirsty traveller when he hath found a fountain, and drink of every water near her: by every hedge will she sit down, and open her quiver against every arrow.
13 The grace of a wife delighteth her husband, and her discretion will fatten his bones.
