Salt-Wort
Salt-wort is a plant gathered by destitute outcasts as food. Job 30:4 records their condition: "They pluck salt-wort by the bushes; and the roots of the broom are their food." UPDV uses "salt-wort" where older translations render the Hebrew as "mallows."
The verse appears in Job's lament over the men who now mock him — people so desperate that they ate plants gathered from the wilderness scrub. Salt-wort and broom roots represent survival-level foraging rather than cultivated food.
