'Locks' in the Bible

And Delilah said to Samson, "Until now you have mocked me and told lies to me. Tell me how you can be bound." And he said to her, "If you weave seven locks of my head with warp-threads."

And she put him to sleep on her lap; then she called the men and shaved off seven locks of his head. Then she began to subdue him, and his strength went away from him.
