Mentioned in 2 Samuel 17:28 as having been brought to David when flying from Absalom. They formed a constituent in the bread Ezekiel (4:9) was commanded to make, as they were in general much used as an article of diet. They are extensively cultivated in Egypt and Arabia and Syria.

benz (pol; Arabic ful): A very common product of Palestine; a valuable and very ancient article of diet. The Bible references are probably to the Faba vulgaris (N. D. Leguminosae) or horsebean. This is sown in the autumn; is in full flower-filling the air with sweet perfume-in the early spring; and is harvested just after the barley and wheat. The bundles of black bean stalks, plucked up by the roots and piled up beside the newly winnowed barley, form a characteristic feature on many village threshing-floors. Beans are threshed and winnowed like the cereals. Beans are eaten entire, with the pod, in the unripe state, but to a greater extent the hard beans are cooked with oil and meat.
In Ezekiel 4:9, beans are mentioned with other articles as an unusual source of bread and in 2 Samuel 17:28 David receives from certain staunch friends of his at Mahanaim a present, which included "beans, and lentils, and parched pulse."
