Musar do Rodzaju 4:25

Rabbi Shmuel bar Nachman in Bereshit Rabbah 12,6 says that there are only two instances in which the word Toldot is spelled plene: the example of Ruth we have quoted and Genesis 2,4: אלה תולדות השמים והארץ בהבראם. Why do all the other instances have one letter ו missing? Rabbi Yudan in the name of Rabbi Avin says that this is due to the six (letter 6=ו) items that G–d has withdrawn from Adam. These are: His זיו, his resplendence [all the editions have זיווג which is an obvious error. Ed.], his life (immortality), his physical height, the fruit of the earth, the fruit of the tree, and the luminaries. All of these are to be restored in the world of the future. Another statement made in that Midrash 23,5 concerns Genesis 4,25, where Eve is reported as naming her third son שת, because "G–d has presented me with another offshoot in place of Abel." Rabbi Tanchum comments that Eve looked at the offshoot (seed) and realized that he had originated from a different sphere, and that would eventually be the Messiah.
