Ben Sira 19:28

28 And if for want of power he be hindered from sinning, yet when he findeth opportunity he will do evil.

Ben Sira 19:28 In-Context

26 There is a wicked man that sadly hangeth down his head, but inwardly he is full of deceit,

27 casting down his countenance and making as if he heard not; where he is not known, he will do thee a mischief before thou be aware.

28 And if for want of power he be hindered from sinning, yet when he findeth opportunity he will do evil.

29 A man may be known by his look, and one that hath understanding by his countenance when thou meetest him.

30 A man's attire and excessive laughter and gait show what he is.
