The word rendered "young man" is specially used for "young warriors," e.g. Jeremiah 18:21; Jeremiah 49:26; Jeremiah 51:3. Others following Rashi, take "mother" in the sense of "metropolis," or "chief city", in which case "young man" must be connected with the participle rendered "a spoiler;" but though the word has this sense in 2 Samuel 20:19, it is there coupled with "city," so that no doubt can exist.
