'Signet' in the Bible

And he said, What pledge shall I give thee? And she said, Thy signet, and thy bracelets, and thy staff that is in thine hand. And he gave it her, and came in unto her, and she conceived by him.

"Your signet ring, cord, and the staff in your hand," she suggested. So he gave them to her, had sex with her, and she became pregnant by him. Then she got up and left. Later, she took off her shawl and put on her mourning clothes.

When she was brought forth, she sent to her father in law, saying, By the man, whose these are, am I with child: and she said, Discern, I pray thee, whose are these, the signet, and bracelets, and staff.

Pharaoh removed his signet ring from his hand and put it on Joseph’s hand, clothed him with fine linen garments, and placed a gold chain around his neck.
