Job 9:19-21

EJ2000(i) 19 If we were to speak of his strength, he is certainly strong; and if of his judgment, who shall cause us to meet? 20 If I justify myself, my own mouth shall condemn me: if I say, I am perfect, he shall prove me perverse. 21 If I say I am imperfect, I know not my soul; I would condemn my life.
