Midrash su Salmi 85:12

Our Rabbis were taught: It happened with the King Monbas, who had distributed his treasure and that of his parents, in the years of famine, that his brothers and the whole household murmured against him, saying: "Your ancestors saved [treasures] and increased the savings of their ancestors, and you distribute thine and that of thy ancestors." And he rejoined: "My ancestors stored up treasures here below, and I store up treasures in heaven, as it is said (Ps. 85, 12) Truth will grow up out of the earth and righteousness will look down from heaven. My ancestors stored away [treasures] in a place which could be reached by a [human] hand, but I have stored away in a place that can be reached by no [human] hand, as it is said (Ib. 89, 15) Righteousness and justice are the prop of Thy throne; kindness and truth precede Thy presence. My ancestors stored away [treasures] which yielded them no interest, and I have stored away [treasures] which yield interest, as it is said (Is. 3, 10) Say ye to the righteous, that he hath done well; for the fruit of their doing shall they eat. My ancestors have stored away money in their treasury, but I have stored away the saved souls in my treasury, as it is said (Prov. 11, 30) The fruit of the righteous is of the tree of life; and the wise draweth souls to himself. My ancestors have stored away for their descendants, but I have saved for myself, as it is said (Deut. 34, 13) … and unto thee shall it be as righteousness before the Lord thy God. My ancestors have stored away [treasures] for this world, but I have stored away [treasures] for the world to come, as it is said (Is. 58, 8) … and before thee shall go thy righteousness; the glory of the Lord shall be thy reward."

R Ami said again: "Rain falls only for the sake of those who have faith in God; as it is said (Ps. 85, 12) Truth springeth out of the earth and righteousness hath looked down from heaven." R. Jochanan said: "He who makes himself righteous (strives for righteousness) [here] below, is judged righteously (strictly) above; as it is said: "Truth springeth out of the earth and righteousness hath looked down from heaven." R. Chiya b. Abin, in the name of R. Huna, made the same inference from the following (Ps. 90, 11) Which is like the fear of thee. Resh Lakish made the inference from the following (Is 64, 4) Thou acceptest him that joyfully worked righteousness, those that remembered Thee in Thy ways; behold, thou wast wroth, and we sinned upon them have we stayed of old, that we might be saved?

Another interpretation (of Deut. 16:18): RIGHTEOUS JUDGMENT. During the time that they judge righteously, they effect righteousness with the people, as stated (in Ps. 85:12 [11]): FAITHFULNESS SHALL SPRING UP FROM THE LAND WHILE RIGHTEOUSNESS LOOKS DOWN FROM HEAVEN. During the time that a faithful judgment springs up from the land, the Holy One effects righteousness with the people. He also saves them from divine punishment and afflictions, while good will comes into the world.
