Commentary for Judges 15:14

הוּא־בָ֣א עַד־לֶ֔חִי וּפְלִשִׁתִּ֖ים הֵרִ֣יעוּ לִקְרָאת֑וֹ וַתִּצְלַ֨ח עָלָ֜יו ר֣וּחַ יְהוָ֗ה וַתִּהְיֶ֨ינָה הָעֲבֹתִ֜ים אֲשֶׁ֣ר עַל־זְרוֹעוֹתָ֗יו כַּפִּשְׁתִּים֙ אֲשֶׁ֣ר בָּעֲר֣וּ בָאֵ֔שׁ וַיִּמַּ֥סּוּ אֱסוּרָ֖יו מֵעַ֥ל יָדָֽיו׃

When he came unto Lehi, the Philistines shouted as they met him; and the spirit of the LORD came mightily upon him, and the ropes that were upon his arms became as flax that was burnt with fire, and his bands dropped from off his hands.
