'Cord' in the Bible

He said, "What pledge should I give you?" She replied, "Your seal, your cord, and the staff that's in your hand." So he gave them to her and had sex with her. She became pregnant by him.

While they were bringing her out, she sent word to her father-in-law: "I am pregnant by the man to whom these belong." Then she said, "Identify the one to whom the seal, cord, and staff belong."
