Génesis 7:6 Midrash: Seder Olam Rabbah, Midrash Tanchuma Buber & Bereshit Rabbah

From Adam to the Flood was 1656 years, and this is their enumeration: Adam 130, Seth 105, Enosh 90, Kenan 70, Mahalalel 65, Jared 162, Enoch 65, Methuselah 187, Lamech 182, and Noah was six hundred years old, etc." (Genesis 7, 6). Enoch buried Adam, and lived after him 57 years. Methuselah exhausted his days just before the Flood. From the Flood to the division [of languages] was 340 years. Noah lived ten years after the division [of languages]. Our father Abraham was at the division [of languages] 48 years old. Rabbi Yosei said: Eber was so great a prophet that he [preemptively] named his son Peleg ["division"], [aided] by the Holy Spirit. [Eber having foreseen what was to come] as it says "in his days the earth was divided" (Genesis 10, 25).

Another interpretation: Lest the nations of the world say: He behaves like a brute with you. That is to say: When the generation of the flood came, he destroyed them with water, as stated (in Gen. 7:6): WHEN THE FLOODWATERS CAME UPON THE EARTH. And similarly, when the generation of the dispersion came, he destroyed them. And similarly, when the Egyptians came, he drowned them in water. And also in the case of these whom he has called (in Exod. 4:22) ISRAEL, MY FIRST-BORN SON, here he is destroying (mekhalleh) them! <He is> like that Lilith (keLilit). When she does not find anything else, she turns on children. So (in Numb. 14:16): BECAUSE THE LORD WAS NOT ABLE TO BRING THIS PEOPLE INTO THE LAND WHICH HE HAS SWORN <TO GIVE> THEM, HE HAS SLAUGHTERED THEM IN THE DESERT. Moses said: Sovereign of the World, (according to vs. 14) THAT YOU, O LORD, ARE SEEN FACE TO FACE (literally: EYE TO EYE). What is the meaning of THAT <YOU> … ARE SEEN EYE TO EYE ('YN B'YN)?¹⁴Similarly Deut. R. 5:13. R. Simeon ben Laqish said: See, the scales are balanced (rt.: 'YN). You say (in Numb. 14:12): I WILL SMITE THEM WITH PESTILENCE AND DISPLACE THEM; but I am saying (in vs. 19): PLEASE PARDON. We shall see whose <utterance> will stand. The Holy One said to him: By your life, Moses, yours shall stand, while mine is null <and void>. Thus it is stated (in Numb. 14:20): THEN THE LORD SAID: I HAVE PARDONED THEM AS YOU ASKED. But nevertheless, the decree of the Holy One which he had uttered to Moses (in Numb. 14:12): THEN I WILL MAKE YOU INTO A NATION THAT IS GREATER AND MORE NUMEROUS THAN THEY, <that decree> was not repealed. He raised up from him sixty myriads, and in the world to come the Holy One shall gather them. Thus it is stated (in Is. 49:12): LOOK! THESE ARE COMING FROM AFAR. AND LOOK! THESE ARE FROM THE NORTH AND FROM THE SEA (i.e., FROM THE WEST), AND THESE FROM THE LAND OF SINIM. Moreover, the exiles shall come with them, also the tribes who are located beyond <the River> Sambatyon¹⁵Gk.: Sabbatikos (“Sabbatical”). See Targum Pseudo-Jonathan, Exod. 34:10; ySanh. 10:6 or 5 (29c); Gen. R. 73:6; Lam. R. 2:5 (9); PR 31:10; above, Gen. 10:17, it was beyond, or on an island in, this legendary river that at least some of the ten tribes were exiled. See also Tanh., Exod. 9:33; Gen. R. 11:5, PR 23:8; according to which the river carried stones in its current during the whole week but rested on the Sabbath. See also Pliny, HN 31:18 (24); Sanh. 65b. Cf. Josephus, BJ 7:5:1 (96–99), according to whom the Sabbath was the only day on which the river flowed. and beyond the darkness.¹⁶Cf. Ezek. 34:12. They shall be gathered and come to Jerusalem. It is concerning them that Isaiah has said (in Is. 49:9): SAYING TO THE PRISONERS: GO FORTH, <i.e.,> to those who are located beyond the Sambatyon. (Ibid., cont.:) TO THOSE WHO ARE IN DARKNESS: SHOW YOURSELVES.¹⁷Higgalu. The verb can also mean “be exiled. These are those who are located beyond the cloud of darkness. (Ibid., cont.:) THEY SHALL PASTURE ALONG THE ROADS, AND {UPON} [IN ALL] THE HEIGHTS SHALL BE THEIR PASTURE. These are those who are located in Daphne near Antioch.¹⁸According to ySanh. 10:6 or 5 (29c) the exiles were divided into three parts: one beyond the Sambatyon River, one to Daphne at Antioch, and one into a cloud cover. At that time they shall be redeemed and come to Zion with gladness. Isaiah has said (in Is. 51:11): SO LET THOSE RANSOMED BY THE LORD RETURN AND COME TO ZION WITH EXALTATION, WITH JOY EVERLASTING UPON THEIR HEADS. LET THEM ATTAIN JOY AND GLADNESS; MAY SORROW AND SIGHING FLEE.

“And Noah was six hundred years old, and the flood was water upon the earth” (Genesis 7:6).
“And Noah was six hundred years old, and the flood was water…” – Rabbi Yehuda and Rabbi Neḥemya, Rabbi Yehuda says: The year of the Flood is not included in the tally [of Noah’s years].¹⁹The Flood began when Noah was six hundred years old, he lived for three hundred and fifty years after the Flood (Genesis 9:28), and the Flood lasted an entire year. Yet the total tally of Noah’s years is given as nine hundred and fifty (Genesis 9:29). Rabbi Neḥemya said to him: Even though it is not included in the tally [of Noah’s years] it is included in the calendrical solar and lunar calculations.²⁰Calendrical calculations are based on the number of years after Creation. For these calculations, the year of the Flood is not omitted.
“Noah, and his sons, and his wife and his sons’ wives with him, came into the ark, because of the water of the flood” (Genesis 7:7).
“Noah, and his sons, and his wife [… came into the ark, because of the water of the flood]” – Rabbi Yoḥanan said: Noah was lacking in faith; if the water had not reached up to his ankles, he would not have entered the ark.
