18 Consider now from this day and upward, from the four and twentieth day of the ninth month, even from the day that the foundation of the LORD'S temple was laid, consider it.
19 Is the seed yet in the barn? yea, as yet the vine, and the fig tree, and the pomegranate, and the olive tree, hath not brought forth: from this day will I bless you.
20 And again the word of the LORD came unto Haggai in the four and twentieth day of the month, saying,
21 Speak to Zerubbabel, governor of Judah, saying, I will shake the heavens and the earth;
22 And I will overthrow the throne of kingdoms, and I will destroy the strength of the kingdoms of the heathen; and I will overthrow the chariots, and those that ride in them; and the horses and their riders shall come down, every one by the sword of his brother.
23 In that day, saith the LORD of hosts, will I take thee, O Zerubbabel, my servant, the son of Shealtiel, saith the LORD, and will make thee as a signet: for I have chosen thee, saith the LORD of hosts.
I encourage you to meditate on Haggai recognizing that Zerubabbel and Jeshua are shadows of the two witnesses of Revelation. They're role is to lead the Remnant to establish the latter House of God.
Zechariah 4 further connects Zerubabbel to the two witnesses by describing the olive trees and lamp stands. Then in verse 9:
"The hands of Zerubbabel have laid the foundation of this house; his hands shall also finish it; and thou shalt know that the LORD of hosts hath sent me unto you."
Now look at Malachi 3:1 "Behold, I will send my messenger, and he shall prepare the way before me: and the Lord, whom ye seek, shall suddenly come to his temple, even the messenger of the covenant, whom ye delight in: behold, he shall come, saith the LORD of hosts."
And read Malachi 4, speaking of this messenger; he is Elijah.
Yes this is prophecy of John the baptist, but didn't Jesus also say that John came in the spirit of Elijah?
The ninth month counting from the first month, the month of Passover, that places us in the month we call December. Could we see the two witnesses revealed this December? It may be a December or two away also.
