FLAX (pishtah).—The plant Linum usitatissimum, and the prepared fibres used for making linen. It was early cultivated in Palestine (Jos_2:6); the failure of the flax was one of God’s judgments (Hos_2:9). The plant is about two to three feet high, with pretty blue flowers; the flax is said to be ‘bolled’ (Exo_9:31) when the seed vessels reach maturity and the plant is ready for gathering. The stalks were dried on the housetops (Jos_2:6), and then soaked in water and the fibre combed out (Isa_19:9 RV [Note: Revised Version.] ). The ‘tow’ of Isa_43:17 is teased-out flax. The oil of the seeds is the well-known linseed oil.
