'Flax' in the Bible

And when he came unto Lehi, the Philistines shouted against him: and the Spirit of the LORD came mightily upon him, and the cords that were upon his arms became as flax that was burnt with fire, and his bands loosed from off his hands.

The ambush [was] sitting [in wait] for her in an inner room. And she said to him, "[The] Philistines [are] upon you Samson!" And he snapped the bowstrings just as flax fiber snaps when it comes close to fire. And [the secret of] his strength remained unknown.
