Midras Yesaya 45:17: Mekhilta DeRabbi Yishmael, Ein Yaakov (Glick Edition), Midrash Tehillim & Midrash Tanchuma

The tenth (song) in time to come, viz. (Isaiah 42;10) "Sing to the L–rd a new song, His praise from the end of the earth (Ibid. 48:42) "Say: The L–rd has redeemed His servant Jacob. All of the (other) songs are denominated in the feminine ("zoth"). Just as a female bears (and then travails again), so, the past salivations were followed by subjugation. But the future (ultimate) redemption will not be followed by subjugation — wherefore it is denominated in the masculine ("zeh" [viz. Isaiah 26:1]). As it is written (Jeremiah 30:6) "Ask now and see if a male has ever given birth. Why, then, do I see that every man puts his hands upon his loins (as a woman giving birth?") For just as a male does not bear (and thus travail), so, the future redemption will not be followed by subjugation. As it is written (Isaiah 45:17) "Israel will be saved by the L–rd, an eternal salvation. You will not be ashamed or abashed forever."

R. Elazar said: "At three places the Holy spirit appeared: At the court of Shem, in the court of the prophet Samuel, and in the court of King Solomon. At the court of Shem, as it is written (Gen. 38, 26) And Juda acknowledged them and said, She hath been more righteous than I. And whence did he know? Perhaps just as he was with her, so was some one else. Therefore a Heavenly voice was heard: I have decided that so is it to be. In the court of Samuel, as it is written (I. Sam. 12, 5) And he answered, He is witness. Why He? It ought to be they! Hence a Heavenly voice was heard, I witness that so it is. And in the court of King Solomon, as it is written (I. Kin. 3, 17) The king then answered and said, Give her the living child and do not slay it; She is its mother. And whence do we know that it really was so, perhaps she deceived him? Hence the last words, she is its mother, were said by a Heavenly voice." Said Raba: "If it were based merely upon the Scripture, all of them could be objected to, but this is shown by tradition."

"They shall be ashamed and dismayed." The sages say that in the future, God will take the righteous and show them Gehenna (Hell) and the empty places within it, and say to them, "These places are empty for you. You have merited them by doing good deeds, and you will inherit Gan Eden (Paradise)." Similarly, the wicked will be taken and shown Gan Eden with empty places within it, and God will say to them, "These places are empty for you and your friends, but you have obligated yourselves with evil deeds, and you will inherit Gehenna." Rabbi Yehoshua ben Levi said that God does not curse the wicked except with shame. Furthermore, He multiplies their curse, as it is written, "They shall be ashamed and dismayed exceedingly." And when God blesses the righteous, He multiplies their blessings, as it says "No shame, no humiliation, ever again for those who keep my commands" (Isaiah 45:17), and "You shall eat abundantly and be satisfied, and you shall praise the name of the Lord your God, who has dealt wondrously with you" (Joel 2:26).
