Judges 16:7 YLT

⁵  and the princes of the Philistines come up unto her, and say to her, 'Entice him, and see wherein his great power 'is', and wherein we are able for him -- and we have bound him to afflict him, and we -- we give to thee, each one, eleven hundred silverlings.'

⁶  And Delilah saith unto Samson, 'Declare, I pray thee, to me, wherein thy great power 'is', and wherewith thou art bound, to afflict thee.'

⁷  And Samson saith unto her, 'If they bind me with seven green withs which have not been dried, then I have been weak, and have been as one of the human race.'

⁸  And the princes of the Philistines bring up to her seven green withs which have not been dried, and she bindeth him with them.

⁹  And the ambush is abiding with her in an inner chamber, and she saith unto him, 'Philistines 'are' upon thee, Samson;' and he breaketh the withs as a thread of tow is broken in its smelling fire, and his power hath not been known.
