And Dalila said to him again: How long dost thou deceive me, and tell me lies? Shew me wherewith thou mayest be bound. And Samson answered her: If thou plattest the seven locks of my head with a lace, and tying them round about a nail, fastenest it in the ground, I shall be weak.
וַתֹּ֨אמֶר דְּלִילָ֜ה אֶל־שִׁמְשׁ֗וֹן עַד־הֵ֜נָּה הֵתַ֤לְתָּ בִּי֙ וַתְּדַבֵּ֤ר אֵלַי֙ כְּזָבִ֔ים הַגִּ֣ידָה לִּ֔י בַּמֶּ֖ה תֵּאָסֵ֑ר וַיֹּ֣אמֶר אֵלֶ֔יהָ אִם־תַּאַרְגִ֗י אֶת־שֶׁ֛בַע מַחְלְפ֥וֹת רֹאשִׁ֖י עִם־הַמַּסָּֽכֶת׃
One Church Father comments on this verse
For a third time, he chose not to disclose the secret completely, yet he shared a bit more: if the seven locks of his hair were allowed to fall freely and woven into a loom, his strength would leave him. And indeed, on one occasion, he was able to thwart the cunning scheme of the plotters.
