In the Hebrew Bible, the use of "עם הארץ" extends from the times of the monarchy and the Babylonian exile to the post-exilic period, but there has always been a debate about its specific reference. This article investigates what it refers to in the monarchy period based on related events and texts in 2 Kings, in order to provide a new perspective for further exploring the social system of ancient Israel and the formation of the ancestral stories. "עם הארץ" plays an important role in the succession of some kings whose mothers originate from the Shephelah, Beersheba and the Negev areas. Accordingly, this article argues that " עם הארץ " refers to those nobilities who belong to the same clans or tribes with the queen mothers. Because these nobilities can influence and represent the interests of common people in their place, this term also designates the common people in these areas. From the 9th to 6th BCE, the Judahite kingdom did not control these areas all the time. Therefore, those nobility and common people were called "עם הארץ" so as to distinguish them from the inhabitants of Jerusalem and the men of Judah.
