'Without Sin' in the Bible

But as they continued to ask Him, He lifted Himself up and said to them, He who is without sin among you, let him cast the first stone at her.

For we do not have a high priest who cannot be touched with the feelings of our infirmities, but was in all points tempted just as we are, yet without sin.

so Christ was once offered to bear the sins of many. And to those who look for Him He shall appear the second time without sin to salvation.
