'Unnoticed' in the Bible

“Others snatch the fatherless [infants] from the breast [to sell or make them slaves],And against the poor they take a pledge [of clothing].

Now the man who had been healed did not know who it was, for Jesus had slipped away [unnoticed] since there was a crowd in that place.

Therefore God overlooked and disregarded the former ages of ignorance; but now He commands all people everywhere to repent [that is, to change their old way of thinking, to regret their past sins, and to seek God’s purpose for their lives],

Now this matter arose because of the false brothers with false pretenses who slipped in unnoticed to spy on our freedom that we have in Christ Jesus, to make us slaves.

For some people have slipped in among you unnoticed. They were written about long ago as being deserving of this condemnation because they are ungodly. They turn the grace of our God into uncontrollable lust and deny our only Master and Lord, Jesus the Messiah.
