spoil: what is seized and carried off from a defeated enemy, whether the plundered goods themselves or the experience of being plundered
This is a word for plunder, the goods and livestock that a victorious army strips from the people it beats and hauls away. It belongs to the later books of the Hebrew Bible, turning up in Chronicles, Ezra, Nehemiah, Esther, and Daniel, and it usually names the prize itself: the sheep and camels driven home, the valuables gathered up, the loot a raiding party divides.
The same word can also name the flip side of that scene, the experience of being on the losing end. When a people is "given to plunder," the word points not to the goods but to the fate: to be stripped, overrun, and carried off. So one term holds both the winner's haul and the loser's ruin.
Hebrew has a small family of overlapping words for spoil. The closest is בַּז, an older and more widespread word for the same thing, while שָׁלָל is the standard, common term for the spoils of war. This later form sits alongside them, favored by the writers of the books composed after the exile.
