'In that Day' in the Bible

On that day,’ declares the Lord of hosts, ‘I will take you, Zerubbabel, the son of Shealtiel, My servant,’ declares the Lord, ‘and I will make you [through the Messiah, your descendant] like a signet ring, for I have chosen you [as the one with whom to renew My covenant to David’s line],’” declares the Lord of hosts.
