'Flax' in the Bible

for their mother hath played the harlot; she that conceived them hath done shamefully; for she said, I will go after my lovers, that give me my bread and my water, my wool and my flax, mine oil and my drink.

Therefore will I take back my grain in the time thereof, and my new wine in the season thereof, and will pluck away my wool and my flax which should have covered her nakedness.
