Job 42

2 “I know that you can do all things; no purpose of yours can be thwarted. 3 You asked, ‘Who is this that obscures my plans without knowledge?’ Surely I spoke of things I did not understand, things too wonderful for me to know. 4“You said, ‘Listen now, and I will speak; I will question you, and you shall answer me.’5My ears had heard of you but now my eyes have seen you.6Therefore I despise myself and repent in dust and ashes.”
