It is necessary for Yeshua to be a blood descendant of Israel, according to Torah, in order for Yeshua to be Kinsman-Redeemer for all of Israel (Lev. 25:25).
It is here that we are told that John would be the one who would perform the prophesied works of Elijah before the great and terrible day of Yahweh (Mal. 4:5-6). John is going to turn the hearts of the people back to Torah to make ready a people prepared for Elohim.
This was a picture of the Kingdom when it comes. Transfiguration essentially means “transformed.” This was a picture of Yeshua in His resurrected state along with Elijah and Moses. In this vision, Moses and Elijah are both transformed also. Moses represents those who have died in faithfulness to Elohim. Elijah represents those who will not taste death before He returns. When Yeshua returns, those dead in Messiah will be raised and those still alive will be caught up in the air to be with Him. We do not know what we will be like, but we know we will be like Him (1 John 3:2).
