הלכה אויף דברים 4:4

How superior is the degree of repentance! But yesterday was this sinner separated from the Lord God of Israel, even as it is said:" But your iniquities have separated between you and your God" (Is. 59.2); cries, but received no answer, even as it is said:" "Yea, when ye make many prayers, I will not hear" (Ibid. 1.15); does obey commandments, but they are thrown back in his face, even as it is said: "Who hath required this at your hand, to trample My courts"? (Ibid.–12), and, "Oh that there were even among you that would shut the doors, that ye might not kindle fire on Mine altar in vain!" (Mal. 1.10). But to-day he is connected with the Shekinah, even as it is said: "But ye that did cleave unto the Lord your God are alive every one of you this day" (Deut. 4.4); he cries and receives answer momentarily, even as it is said: "And it shall come to pass that before they call, I will answer" (Is. 65.24); he observes commandments, and they are received with pleasure and joy, even as it is said: "For God hath already accepted thy works" (Ecc. 9.7); moreover, his works are pleasurably anticipated, even as it is said: "Then shall the offering of Judah and Jerusalem be pleasant unto the Lord, as in the days of old, and as in ancient years" (Mal. 3.4).

(Peh) A man shall give redemption for his soul by doing good to the good – which are the Torah scholars – when he benefits them with his property. As through this, he merits to give life to his soul at the time that ‘corpses will arise.’ It is like the statement of [the Sages], may their memory be blessed [in the] chapter [entitled] HaNoseh (Ketuvot 111b):
Rabbi Elazar said, “The common, uneducated people (amei ha-arets) will not live [in the future to come].” Rabbi Yocḥanan said to him, “Their master, (i.e. God), is not pleased that you say this about them.” He said to him, ‘I expound it from a […] verse […] (Isaiah 26:19), ‘For Your dew is as the dew of light, etc.’” When he saw that [Rabbi Yocḥanan] was grieved, he said to him, “My teacher, I have found a remedy for them from the Torah, ‘But You who cleave to the Lord [your God, are alive every one of you this day]’ (Deut. 4:4). But is it possible to cleave to the Divine Presence? Isn’t it written, ‘For the Lord your God is a devouring fire’ (Deut. 4:24)? Rather, [it teaches] that anyone […] who conducts business on behalf of Torah scholars, and one who benefits Torah scholars with his property, [it is] as though he is cleaving to the Divine Presence, [and it is written, ‘are alive every one of you this day’].”  [See there.]
Behold that the revival of the dead is [dependent] only upon the dew of Torah – only one who [utilizes his wealth to] benefit Torah scholars has their dew, like the matter of Zevulun and Yissachar.⁵⁵See Bamidbar Rabbah 13:17 which speaks about such an arrangement between these two tribes. And this is the intention of their statement, may their memory be blessed, in the chapter [entitled] Chelek (Sanhedrin 90a), “These are the ones that do not have a share in the world to come: One who says that the revival of the dead is not from the Torah.”⁵⁶The traditional meaning of this – as understood in the Talmud – is that he denies that there is a source in the Torah for the revival of the dead. And they say [further on the same page] in the Talmud, “He denied the revival of the dead; therefore he has no resurrection.” Its explanation is that even though he agrees with the principle of resurrection, he says that it is not caused by Torah and [so] denies its cause – [such a one] has no resurrection. [This is] since there is no cause for it besides Torah – his or that of others who benefit from him. And since he denies this, it will not resurrect him. Indeed, every man should believe that this is the essence of the resurrection; and then he will merit to arise with ‘the sleepers of Chevron,’⁵⁷This is referring to the patriarchs and matriarchs buried in Chevron. and rejoice in the joy of Zion, may it be built and established speedily in our days!
