'Unnoticed' in the Bible

But the man who had been cured did not know who it was; for Jesus had passed out unnoticed, there being a crowd in the place.

For certain persons have crept in unnoticed--men spoken of in ancient writings as pre-destined to this condemnation--ungodly men, who pervert the grace of our God into an excuse for immorality, and disown Jesus Christ, our only Sovereign and Lord.
