Midrash sobre Jeremías 17:18

Acher asked this question of R. Mair, after he had gone forth into the evil courses: "What is the meaning of the passage (Ecc. 7, 14) Also this hath God made in equal measure with the other?" He answered him: "Everything which the Holy One, praised be He! — created. He created with its counterpart. He created mountains and He created hills; He created seas and He created rivers." Acher said to him: "R. Akiba thy teacher did not say so, but he explained it as meaning that He created righteous and He created sinners; He created the garden of Eden and He created Gehenna. To every individual belongs two shares, one in the garden of Eden and the other in Gehenna. If one is meritorious and righteous, he receives his own portion and that of his neighbor in the garden of Eden. If he has incurred guilt, he receives his own portion and that of his neighbor in Gehenna." R. Mesharshia said: "Where is the passage to prove this? Concerning the righteous, it is written (Is. 61,7) Therefore in their hand shall they inherit a twofold (portion), and concerning the wicked, it is written (Jer. 17, 18) And strike them with a double breach."
