Job 30:4
Brenton's English Septuagint · Berean Standard Bible
Who compass the salt places on the sounding [shore], who had salt [herbs] for their food, and were dishonourable and of no repute, in want of every good thing; who also ate roots of trees by reason of great hunger.
They plucked mallow among the shrubs, and the roots of the broom tree were their food (note: Or their fuel).
