'Without Sin' in the Bible

Who can say, "I have made my heart pure. I am clean and without sin?"

But when they continued asking him, he looked up and said to them, "He who is without sin among you, let him throw the first stone at her."

For we do not have a high priest who cannot be touched with the feeling of our infirmities, but one who has been in all points tempted like we are, yet without sin.

so Christ also, having been offered once to bear the sins of many, will appear a second time, without sin, to those who are eagerly waiting for him for salvation.
