דבל
The verb דבל (dbl) isn't used in the narrative of the Bible, but it probably existed in the time in which the Bible plays. It occurs in Arabic in the sense of to collect, or make into lumps, and it's rumored to also exist in Ethiopian.
In the narrative of the Bible only exists the feminine noun דבלה (debela), which denotes a lump of pressed figs, or a cake made thereof (1 Samuel 30:12, 2 Kings 20:7, 1 Chronicles 12:40).
