Flax: (Heb. pishtah, i.e., "peeled", in allusion to the fact that the
stalks of flax when dried were first split or peeled before
being steeped in water for the purpose of destroying the pulp).
This plant was cultivated from earliest times. The flax of Egypt
was destroyed by the plague of hail when it "was bolled", i.e.,
was forming pods for seed (Ex. 9:31). It was extensively
cultivated both in Egypt and Israel. Reference is made in
Josh. 2:6 to the custom of drying flax-stalks by exposing them
to the sun on the flat roofs of houses. It was much used in
forming articles of clothing such as girdles, also cords and
bands (Lev. 13:48, 52, 59; Deut. 22:11). (See LINEN T0002296.)
