'Thief' in the Bible

“Truly, truly, I say to you, he who does not enter by the door into the fold of the sheep, but climbs up some other way, he is a thief and a robber.

The thief comes only to steal and kill and destroy; I came that they may have life, and have it abundantly.

Now he said this, not because he was concerned about the poor, but because he was a thief, and as he had the money box, he used to pilfer what was put into it.
