Esther 3

Verse 10

signet ring --The face of these rings included an engraving that would be utilized to stamp an image on a document, particularly when sealing it. This functioned as the king’s personal identification symbol. During the Persian period, signet rings were commonly imprinted on wet clay or wax that was allowed to dry, thereby sealing documents such as scrolls. The imprint of the king’s signet ring essentially served as his signature. - FSB
