'Seal' in the Bible

And he said, "What [is] the pledge that I must give to you?" And she said, "your seal, your cord, and your staff that [is] in your hand." And he gave [them] to her and went in to her. And she conceived by him.

She was brought out, but she sent to her father-in-law saying, "By the man to whom these [belong] I have conceived." And she said, "Now discern to whom these [belong]: the seal and cord and the staff."
