28 When one builds and another destroys, what benefit do they have from their labor?
29 When one prays and another curses, whose voice will God heed?
30 He who washes himself after touching the dead, and then touches him again, what was the benefit of his washing?
31 Similarly, a man who fasts for his sins, and then does the same again, what was the benefit of his humbling himself? Who will heed his prayer?
