'Without Sin' in the Bible

There was a man in the land of Uz whose name was Job. He was without sin and upright, fearing God and keeping himself far from evil.

And the Lord said to the Satan, Have you taken note of my servant Job, for there is no one like him on the earth, a man without sin and upright, fearing God and keeping himself far from evil?

And the Lord said to the Satan, Have you taken note of my servant Job, for there is no one like him on the earth, a man without sin and upright, fearing God and keeping himself far from evil? and he still keeps his righteousness, though you have been moving me to send destruction on him without cause.

Truly, God will not give up him who is without sin, and will not take evil-doers by the hand.

I am clean, without sin; I am washed, and there is no evil in me:
