Judges 16:13-17

¹³And Dalida said to Sampson, Behold, you have deceived me, and told me lies; tell me, I entreat you, wherewith you may be bound: and he said to her, If you should weave the seven locks of my head with the web, and should fasten them with the pin into the wall, then shall I be weak as another man.

¹⁴And it came to pass when he was asleep, that Dalida took the seven locks of his head, and wove them with the web, and fastened them with the pin into the wall, and she said, The Philistines are upon you, Sampson: and he awoke out of his sleep, and carried away the pin of the web out of the wall.

¹⁵And Dalida said to Sampson, How say you, I love you, when your heart is not with me? this third time you have deceived me, and have not told me wherein is your great strength.

¹⁶And it came to pass as she pressed him sore with her words continually, and straitened him, that his spirit failed almost to death.

¹⁷Then he told her all his heart, and said to her, A razor has not come upon my head, because I have been a holy one of God from my mother's womb; if then I should be shaven, my strength will depart from me, and I shall be weak, and I shall be as all other men.
