'Tow' in the Bible

Now she had liers-in-wait abiding in the inner chamber. And she said unto him, The Philistines are upon thee, Samson. And he brake the withes, as a string of tow is broken when it toucheth the fire. So his strength was not known.

And the strong shall be as tow, and his work as a spark; and they shall both burn together, and none shall quench them.
