'Son of Perdition' in the Bible

and there was much disputing about him among the crowd. Some would say, "He is a good man." Others. "No! he is misleading the people." "While I was with them I kept them by the power of thy name which thou hast given me. I guarded them, and none of them was lost except the son of perdition, that the Scripture might be fulfilled.

While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled.

Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;

the son of perdition, who opposeth and exalteth himself above all that is called God, or the object of worship; so that he sits as God in the temple of God, shewing himself that he is God.
