Interesting Midrash I read today.

The fifth house [in the heavenly Paradise] is built of onyx and jasper stones, and inlaid stones, and silver and gold, and good pure gold. And around it are rivers of balsam, and before its door flows the River Gihon. And [it has] a canopy of all trees of incense and good scent. And[in it are] beds of gold and silver, and embroidered garments. And there sits Messiah ben David and Elijah and Messiah ben Ephriam. And there is a canopy of incense trees as in the Sanctuary which Moses made in the desert. And all its vessels and pillars are of silver, its covering is gold, its seat is purple. And in it is Messiah ben David who loves Jerusalem. Elijah of blessed memory takes hold of his head, places it in his lap and holds it, and says to him: “Endure the sufferings and the sentence of your Master who makes you suffer because of the sin of Israel.” And thus it is written; He was wounded because of our transgressions, he was crushed because of our iniquities (Isaiah 53:5) until the time when the comes. (“Midrash Konen” BhM 2:29-30)
