Kommentar zu Dewarim 4:24

That is that He commanded us to associate with the sages, to gather with them and to constantly be involved with them in all manner of work and interaction - in eating and drinking and business, so that it comes to us to imitate their actions and believe the truth of their words. And that is His, may He be exalted, saying, "and to Him shall you cling" (Deuteronomy 10:20). And this command has also already been repeated - "and to cling to Him" (Deuteronomy 11:22). And in the Sifrei (Sifrei Devarim 49:2), it appears, "'And to cling to Him' - cling to the sages and their students." And they accordingly brought a proof about this obligation of a person - to marry the daughter of a Torah scholar, to feed Torah scholars and to give them business - from His saying, "and to Him shall you cling": And they said, "And is it possible for a person to cling to the Divine Presence? And behold, it is written (Deuteronomy 4:24), 'For the Lord, your God, is a consuming fire!' Rather, anyone who marries his daughter to a Torah scholar, or who marries the daughter of a Torah scholar or who benefits a Torah scholar - Scripture considers it as if he clung to the Divine presence." (See Parashat Ekev; Mishneh Torah, Human Dispositions 6.)
