'Thief' in the Bible

Verily, verily, I say unto you, He that entereth not by the door into the fold of the sheep, but climbeth up some other way, the same is a thief and a robber.

The thief cometh not, but that he may steal, and kill, and destroy: I came that they may have life, and may have it abundantly.

Now this he said, not because he cared for the poor; but because he was a thief, and having the bag took away what was put therein.
