In Jeremiah 22:24-30, we see God rejecting Zerubbabel’s Grandfather, Jehoiachin, right before the Babylonian evasion. But God never negated the covenant He had made with king David back in II Samuel 7:11-13, establishing David’s kingdom & throne forever. So we see here in Haggai God using the same language to promise a renewal of the Davidic kingdom through His chosen person, Zerubbabel. The importance of the signet ring here was hugely important, for it was an official insignia used for contracts & other important documents. And later, we find this distinguishing mark used in II Corinthians 1:22, where God’s authority, ownership, and guaranteed protection seals us, not with a wax seal, but with the Holy Spirit in our heart as we read, “He anointed us, set His seal of ownership on us, and put His Spirit in our hearts as a deposit, guaranteeing what is to come.” So just like Zerubbabel, we’ve have been chosen of God & given an eternal promise never to be broken.
