2 Kings 5:2

And the Syrians had gone out by companies
Not regular troops, but a sort of banditti of robbers, which made excursions into the land of Israel, to plunder and carry off what booty they could:

and had brought away captive out of the land of Israel a little maid;
for boys and girls were a part of the booty of such robbers, whom they could sell for money, see ( Joel 3:1 ) . Jarchi and Kimchi say she was a girl of Naaron, a city so called:

and she waited on Naaman's wife;
being either made a present of to the general by those plunderers, or was bought by him of them for his wife's service.
