“‘On that day,’ declares the LORD Almighty, ‘I
will take you, my servant Zerubbabel son of Shealtiel,’ declares the LORD, ‘and
I will make you like my signet ring, for I have chosen you,’ declares the LORD
Almighty.”
From Background Notes [BN] for October 6th & 7th
written by Pastor Bob Brown:
In the present context, the purpose of
the signet ring was to authenticate legal documents, identify property, or
authorize proxy, functioning much like our signature (Jeremiah 32:10-44;
1 Kings 21:8). If one person gave another person his seal, then he thereby
conferred authority and trust. God is making Zerubbabel the equivalent of a
seal in this sense.
