Sirach 34:25

25 He that washeth himself after the touching of a dead body, if he touch it again, what availeth his washing?

Sirach 34:25 In-Context

23 When one buildeth, and another pulleth down, what profit have they then but labour?
24 When one prayeth, and another curseth, whose voice will the Lord hear?
25 He that washeth himself after the touching of a dead body, if he touch it again, what availeth his washing?
26 So is it with a man that fasteth for his sins, and goeth again, and doeth the same: who will hear his prayer? or what doth his humbling profit him?
