The name Arubah appears as the mother of Ben-hesed, one of Solomon's twelve district governors responsible for provisioning the royal household. The name may relate to a root meaning 'mixing' or 'pledging/exchanging.'
The mention of Arubah in Solomon's administrative roster (1 Kings 4) illustrates the complex infrastructure of the united monarchy. Solomon's twelve district system ensured no tribe bore the burden of provisioning alone — each district contributed one month per year. The inclusion of mothers' names in these genealogies reflects the honor given to women in preserving lineage and identity in ancient Israel.
