לְקֵדָ֣ר ׀ וּֽלְמַמְלְכ֣וֹת חָצ֗וֹר אֲשֶׁ֤ר הִכָּה֙ נבוכדראצור [נְבֽוּכַדְרֶאצַּ֣ר] מֶֽלֶךְ־בָּבֶ֔ל כֹּ֖ה אָמַ֣ר יְהוָ֑ה ק֚וּמוּ עֲל֣וּ אֶל־קֵדָ֔ר וְשָׁדְד֖וּ אֶת־בְּנֵי־קֶֽדֶם׃
Of Kedar, and of the kingdoms of Hazor, which Nebuchadrezzar king of Babylon smote. Thus saith the LORD: Arise ye, go up against Kedar, And spoil the children of the east.
Rashi on Jeremiah
Concerning Kedar They were desert dwellers, with neither wall nor city.
