Commentary for Judges 16:19

וַתְּיַשְּׁנֵ֙הוּ֙ עַל־בִּרְכֶּ֔יהָ וַתִּקְרָ֣א לָאִ֔ישׁ וַתְּגַלַּ֕ח אֶת־שֶׁ֖בַע מַחְלְפ֣וֹת רֹאשׁ֑וֹ וַתָּ֙חֶל֙ לְעַנּוֹת֔וֹ וַיָּ֥סַר כֹּח֖וֹ מֵעָלָֽיו׃

And she made him sleep upon her knees; and she called for a man, and had the seven locks of his head shaven off; and she began to afflict him, and his strength went from him.

Rashi on Judges
