Midrash su Salmi 11:7

Another interpretation (of Gen. 6:9): THESE ARE THE GENERATIONS OF NOAH; NOAH WAS A RIGHTEOUS MAN.¹⁸Cf. Tanh. Gen. 2:5. Why is he given the name RIGHTEOUS? Inasmuch as he fed the creatures of the Holy One, he became like his Creator. Thus it is stated (in Ps. 11:7): FOR THE LORD IS RIGHTEOUS; HE LOVES RIGHTEOUS DEEDS. So also Joseph. Inasmuch as he fed the creatures for seven years, he was called righteous, as stated (in Amos 2:6): BECAUSE THEY SELL A RIGHTEOUS < ONE > (i.e., Joseph) FOR SILVER. {Thus, because he fed the creatures for seven years, he was therefore called righteous.}

(Gen. 27:23:) SO HE DID NOT RECOGNIZE HIM BECAUSE HIS HANDS WERE < HAIRY LIKE THE HANDS OF HIS BROTHER ESAU >. He (Isaac) foresaw that the wicked ones were going to arise from him; and he did not want to bless him {since he foresaw Jakum.⁴³I.e., Jakum of Seroroth. See Gen. R. 65:22; cf. M. Ps. 11:7. When Jerusalem was conquered, the world said: They are afraid to enter into the Temple. What did he do? He entered and brought < out > the menorah. When < Isaac > saw him, he did not want to bless Jacob on his account. SO HE DID NOT RECOGNIZE HIM}. When he foresaw that he would repent, there immediately follows (in vs. 27): THEN HE SMELLED THE ODOR OF HIS CLOTHES AND BLESSED HIM…. When Jacob entered, the Garden of Eden (i.e., Paradise) entered with him, as stated (ibid., cont.): LIKE THE ODOR OF A FIELD WHICH THE LORD HAS BLESSED. When Esau entered, Gehinnom entered with him. Thus it is stated (in vs. 33): WHO IS EPHO?⁴⁴The natural translation is: WHO THEN? Now EPHO can only be Gehinnom, since it is stated (in Is. 22:16): THAT YOU HAVE HEWN A TOMB HERE (poh) FOR YOURSELF.

"Righteous and just is He": as it is written (Psalms 11:7) "For the L-rd is righteous and loves righteousness."
