Hebrew: 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 Palestine.
