The Hebrew word for ‘power’ is toqeph and includes ‘strength’ and ‘energy. This word can also be used in place of ‘authority.’
Revelation Chapter 5 – The Scroll
The megillah has seven seals. The Hebrew word ‘seal’ is chatham and means ‘signer’s imprint.’ The ‘signer’s imprint’ came from an individual’s signet ring giving the signer full authority and power to send the message or ‘seal the decree.’ The only one authorized who could break the seal had to be the receiver for the intended message.
