42. He opened the discussion, saying: "And in process of time (lit. 'at the end of days') it came to pass, that Cain brought of the fruit of the ground an offering to Hashem" (Beresheet 4:3). "At the end of days," has a secret meaning; it is "the end of days (Heb. yamim)," WHICH IS IMPURITY, rather than 'the end of right (Heb. yamin; also 'days')', WHICH IS HOLINESS. He rejected the 'end of right (Heb. yamin)' and sought to bring near the "end of days (Heb. yomin)." We have established that it is written: "But go you your way till the end be" (Daniel 12:13). The Holy One, blessed be He, said to Daniel: "But go you your way till the end be." He kept asking Him: 'which end? the end of days or end of right?', until He said to him: 'The end of the right.'
43. This is what David feared, as it is written: "Let me know, Hashem, my end" (Tehilim 39:5), whether the end of the days or the end of the right. And here, BY CAIN, it is written: "And it came to pass" "at the end of days," rather than 'at the end of the right'. Therefore, his offering was not accepted, because it all came from the Other Side.
44. Come and behold: it is written, "And Abel, he also brought" (Beresheet 4:4). What is the meaning of "he also"? Its purpose is to add everything, one within the other - MEANING THAT IN THE OFFERING OF ABEL THERE WAS ALSO A PORTION FOR THE OTHER SIDE, AND IN THE OFFERING OF CAIN THERE WAS ALSO A PORTION FOR HOLINESS. HOWEVER, WITH ABEL, the whole and main part of his offering was to the Holy One, blessed be He, and he gave a portion for the Other Side, as is written: "And of the fat parts thereof" (Ibid.); THE FATTEST AND BEST WAS FOR THE HOLY ONE, BLESSED BE HE. But with Cain, the main was for "the end of days," WHICH IS THE OTHER SIDE, and he gave only a small portion to the Holy One, blessed be He. Therefore, he and his offering were rejected.
45. About Job, it is written: "And his sons used to go and feast... And when the days of their feasting were gone about" (Iyov 1:4-5), and also, "And they used to send and call for their three sisters to eat and drink with them" (Ibid.). This was the main portion HE GAVE to the Other Side, and only afterwards did he offer burnt offerings. Now, a burnt offering (Heb. olah) is male rather than female, and wholly rises (Heb. olah) up, but he did not offer a sacrifice that would properly include it as well, MEANING TO ALSO GIVE A PORTION TO THE OTHER SIDE.
