And one went in and told his lord,.... What the girl had said to her mistress; one of the servants of the house that overheard it; or rather, Naaman went and told his lord the king of Syria; for as this was said to his wife, no doubt she told it to her husband, and not a servant; and the following words require this sense, and is the sense of most Jewish commentators: saying, thus and thus said the maid that is of the land of Israel; who for her wit and beauty might be well known at court by the name of the Israelitish girl.
