a thief: one who takes what belongs to another by stealth.
A thief is someone who takes what belongs to another in secret. That stealth is the heart of the word: a thief slips in unseen, unlike a robber who seizes goods by open force (the violent plunderer, פָּרִיץ). The word names the doer behind the verb גָּנַב, "to steal."
Israel's law handled this crime through repayment rather than blood. A caught thief made restitution, paying back what was taken and more, and a thief who broke in at night could be struck down without guilt. The one exception was grave: stealing a person, not property, was a capital crime, and Deuteronomy 24:7 calls the kidnapper by this same word.
The prophets and poets reach for the thief as a ready picture:
- the shame of a thief caught in the act stands for a nation exposed in its guilt (Jeremiah 2:26)
- an invader slips in through the windows "like a thief" (Joel 2:9)
- corrupt leaders are branded "companions of thieves" (Isaiah 1:23)
In each case the point is the same: something done secretly, shamefully, and against another's right.
