Midrash su Isaia 51:13

{Another interpretation (of Gen. 49:28): AND THIS IS WHAT THEIR FATHER SPOKE TO THEM.} [(Gen. 50:12:) SO HIS CHILDREN DID FOR HIM JUST AS HE HAD COMMANDED THEM.] What did they do? They embalmed him and brought him up < to the land of Israel >.⁸²Tanh., Gen. 12:17; Gen. R. 97, New Version, on 49:29 (= pp. 1228-1229 in the Theodor-Albeck edition); Sot. 13a. What is written (in Gen. 50:10)? WHEN THEY CAME TO THE THORNBUSH THRESHING FLOOR.⁸³THE THORNBUSH THRESHING FLOOR is usually regarded as a proper name, i.e., as GOREN HA’ATAD. Is there a threshing floor for thorns, as it says: TO THE THORNBUSH THRESHING FLOOR? It is simply that these were Canaanites who had taken their crowns and surrounded Jacob's coffin, as a threshing floor when one surrounds it with thorns. R. Eliezer says: When they saw the coffin of our father Jacob, they undid the girdles on their waists and < so > showed honor to our father Jacob.⁸⁴Gen. R. 100(101):6; ySot. 1:10(17b). R. Samuel bar Nahman said: They undid their finger joints; and our masters say: They pointed the finger at Jacob's coffin and said (in Gen. 50:11): THIS IS A SOLEMN MOURNING FOR THE EGYPTIANS. For this reason the Holy One gave them a threshing floor.⁸⁵A sign of fruitfulness in what had been unfruitful, a mere thornbush threshing floor. (Gen. 50:10:) AND HE CARRIED OUT SEVEN DAYS OF MOURNING FOR HIS FATHER. From here we learn that the time for mourning is seven days. They also give evidence for it from here (in Lev. 8:33): AND YOU SHALL NOT GO OUT FROM THE DOOR OF THE TENT OF MEETING FOR SEVEN DAYS. And why do they carry out seven days of mourning rites? < It > corresponds to the seven days of feasting (on a joyous occasion). The Holy One said to them: In this world you have exhibited sorrow in the company of this righteous man and observed a seven-day mourning for him. In the world to come I am turning this mourning into feasting, as stated (in Jer. 31:13): FOR I WILL TURN THEIR MOURNING INTO JOY, COMFORT THEM, AND CHEER THEM IN THEIR GRIEF. Then, just as I comfort them, so I will give comfort to Zion, as stated (in Is. 51:3): TRULY THE LORD HAS COMFORTED ZION; HE HAS COMFORTED ALL ITS RUINS. HE HAS ALSO MADE ITS DESERT LIKE EDEN AND ITS DRY PLAIN LIKE THE GARDEN OF THE LORD. JOY AND REJOICING SHALL BE FOUND IN IT, THANKSGIVING AND THE SOUND OF MUSIC.

And Jacob became very frightened and distressed (Genesis 32,8). Rabbi Pinchos says in the name of Rabbi Re'uven that there were two people that Hashem promised them and nevetheless they were afraid. The chosen of the patriarchs and the chosen of the prophets. The chosen of the patriarchs is Jacob as it states (Psalms 135,4) "For Jacob, Y-H chose for Him" and and Hashem said to him (Genesis 28,15) "And behold I am with you" and at the end, he became frightened as it says "And Jacob became frightened". The chosen of the prophets is Moshe as it says (Psalms 106,23) "Were it not for Moshe His chosen one" and Hashem said to him "For I will be with you" and in the end he became frightened as it says (Numbers 21:34) "And Hashem said to Moshe, don't fear him" Hashem would only say "Don't fear him" to someone who has become afraid. Rabbi Brechiah and Rabbi Chelbo recited in the name of Rabbi Shmuel Bar Nachman who recited in the name of Rabbi Nassan "The Jewish people were worthy of being destroyed in the days of Haman, were it not that they relied on the knowledge of the parents' elder. They said "If Yaacov our patriarch, who was promised security by Hashem and Hashem told hi "And behold I will be with you" and HE became frigthened. How much moreso US. It is this that the prophet accuses Israel of and says to them (Isaiah 51,13) "And you forgot Hashem your maker the one who spread the heavens and founded earth." He said to those people what he would say to you (Jeremiah 31,36) "So said Hashem: If the heavens from above will be measured" if you see that the heavens quake and that the earth quakes, from the inclination of the heavens and earth you wouldn't learn anything other than (Isaiah 51,13) "And you are afraid all your days"

"and he forsook the G-d who made him": as in (Isaiah 51:13) "And you have forgotten the L-rd who made you, who spread out the heavens and founded the earth." And (Jeremiah 2:13) "For two evils have My people committed": The Holy One Blessed be He said to them: As you have meted it out to Me have I meted it out to you (Ibid. 12:7) "I have abandoned My house (the Temple); I have forsaken My inheritance," (Psalms 78:60) "and He abandoned the tabernacle of Shiloh," (Isaiah 2:6) "For you have forsaken your people, house of Jacob."
