'String' in the Bible

Now she had men lying in wait in an inner chamber. And she said to him, "The Philistines are upon you, Samson!" But he snapped the bowstrings, as a string of tow snaps when it touches the fire. So the secret of his strength was not known.

For behold, the wicked bend the bow, they make ready their arrow upon the string, that they may in darkness shoot at the upright in heart.
