The two witnesses patterned the ministries of Moses and Elijah as their callings were incomplete!
The Beloved Disciple recorded what he heard, saw, and experienced by The Holy Spirit in Revelation chapter 11:
4 These are the two olive trees and the two lampstands standing before the God of the earth.
5 And if anyone wants to harm them, fire proceeds from their mouth and devours their enemies. And if anyone wants to harm them, he must be killed in this manner.
6 These have power to shut heaven, so that no rain falls in the days of their prophecy; and they have power over waters to turn them to blood, and to strike the earth with all plagues, as often as they desire.
There were four specific judgments that these two witnesses brought forth. These judgments parallel what is written of in the Old Testament linked to Moses and Elijah:
Elijah spoke by THE SPIRIT in 1st Kings chapter 18:
37 Hear me, O LORD, hear me, that this people may know that You are the LORD God, and that You have turned their hearts back to You again.”
38 Then the fire of the LORD fell and consumed the burnt sacrifice, and the wood and the stones and the dust, and it licked up the water that was in the trench. 39 Now when all the people saw it, they fell on their faces; and they said, “The LORD, He is God! The LORD, He is God!”
And in 1st Kings chapter 17:
1 And Elijah the Tishbite, of the inhabitants of Gilead, said to Ahab, “As the LORD God of Israel lives, before whom I stand, there shall not be dew nor rain these years, except at my word.”
And Jesus confirms the length of time in Luke chapter 4:
25 But I tell you truly, many widows were in Israel in the days of Elijah, when the heaven was shut up three years and six months, and there was a great famine throughout all the land;
THE LORD spoke to Moses in Exodus chapter 7:
19 Then the LORD spoke to Moses, “Say to Aaron, ‘Take your rod and stretch out your hand over the waters of Egypt, over their streams, over their rivers, over their ponds, and over all their pools of water, that they may become blood. And there shall be blood throughout all the land of Egypt, both in buckets of wood and pitchers of stone.'”
20 And Moses and Aaron did so, just as the LORD commanded. So he lifted up the rod and struck the waters that were in the river, in the sight of Pharaoh and in the sight of his servants. And all the waters that were in the river were turned to blood.
In Exodus chapters 8 through 12, Moses brought forth ten plagues on the land:
Waters become blood
Frogs
Lice
Flies
Livestock diseased
Boils
Hail
Locusts
Darkness
Death of the firstborn
7 When they finish their testimony, the beast that ascends out of the bottomless pit will make war against them, overcome them, and kill them.
8 And their dead bodies will lie in the street of the great city which spiritually is called Sodom and Egypt, where also our Lord was crucified.
9 Then those from the peoples, tribes, tongues, and nations will see their dead bodies three-and-a-half days, and not allow their dead bodies to be put into graves.
10 And those who dwell on the earth will rejoice over them, make merry, and send gifts to one another, because these two prophets tormented those who dwell on the earth.
11 Now after the three-and-a-half days the breath of life from God entered them, and they stood on their feet, and great fear fell on those who saw them.
Now that their ministry was completed:
12 And they heard a loud Voice from Heaven saying to them, “Come up here.” And they ascended to heaven in a cloud, and their enemies saw them.
13 In the same hour there was a great earthquake, and a tenth of the city fell. In the earthquake seven thousand people were killed, and the rest were afraid and gave glory to the God of Heaven.
14 The second woe is past. Behold, the third woe is coming quickly.
Jesus met with Moses and Elijah on the Mount of Transfiguration and the parallel of the two witnesses is compelling! It is imperative that we view the linkage of the Old and New Testaments as an integrated message system given to us by FATHER.
