Lucas 9

27 But I say to you, Omein, there are some standing here who will by no means taste mavet until they see the Malchut Hashem.

28 And it came to pass, about a week after these divrei Moshiach, that when he had taken Kefa and Yochanan and Ya’akov, Rebbe Melech HaMoshiach went up to the har to daven. 29 And it came about that while Rebbe Melech HaMoshiach davens, the appearance of his face became different and his kaftan and all his clothing became dazzling white. 30 And two men were conversing with Rebbe Melech HaMoshiach, and these two men were Moshe Rabbeinu and Eliyahu HaNavi, 31 Who appeared in kavod and were speaking of Moshiachʼs Litziat Exodus, which he was about to fulfill in Yerushalayim.
