Midrash su Geremia 6:9

And the Lord said: Behold, they are one people, and they have all one language; and this is what they begin to do, and now nothing will be withholden from them (Gen. 11:6). What is the meaning of the words and now? They mean that though they had rebelled against Him, were contumacious, and had built a tower, the Holy One, blessed be He, stretched out His right hand toward them so that they might repent, as it is said: And now, Israel, what does the Lord thy God require of thee, but to fear the Lord thy God (Deut. 10:12). But they replied: Nothing will be withholden (yibazer) from them. Even if those men were cut off (nivzarim) from the world, they would not repent, as it is said: As a grape-gatherer (bozer) cutteth off the shoots (Jer. 6:9).

(Gen. 11:5, cont.:) WHICH THE CHILDREN OF ADAM HAD BUILT. He said to them: Are you not looking to the ancient ones which were before you? {Thus it is stated in} (Gen. 11:6:) AND THE LORD SAID: THEY ARE ONE PEOPLE AND THEY ALL HAVE ONE LANGUAGE … [AND NOW NOTHING < THEY PROPOSE > WILL BE CUT OFF < FROM THEM >]. Although they rebelled, I extended my right hand to them. So I said to them: Repent, and I will receive you, just as it is stated (in Deut. 10:12): AND NOW, ISRAEL, WHAT DOES THE LORD YOUR GOD ASK [OF YOU] < … >?¹¹³According to Mekhilta de Rabbi Ishmael, Shirata 5, and Gen. R. 38:9, Deut. 10:12 shows that the AND NOW in Gen. 11:6 is a plea for repentance. But they said (in Gen. 11:6): NOTHING < THEY PROPOSE > WILL BE CUT OFF FROM THEM. Even if those people were cut off, they would not repent, as stated (in Jer. 6:9): LIKE A VINTAGER OVER < THE VINE > SHOOTS.
