Musar su Deuteronomio 4:4

We know from Deut. 4,4: ואתם הדבקים בה' אלוקיכם חיים כולכם היום, "And you who have cleaved to the Lord your G–d are all alive this day," that G–d has chosen us from all other nations and elevated us beyond all other languages, i.e. He brought us close to His great Name, something which is the innermost secret of Torah. This is the true meaning of תורת ה' תמימה, that G–d's Torah is perfect. Our attachment, דבקות, to G–d finds its expression in our performance of the commandments contained in the Torah. When we fulfil Torah precepts we serve as G–d's throne, we honour Him. Due to our sins, unfortunately, we have been exiled and the name of G–d is no longer "whole," as our sages have told us.

Come and see the greatness of the eminence of one who upholds the Torah, and benefits a Torah scholar with his possessions and draws close to him, Scripture considering it as if he [thereby] cleaved to the Shechinah. As Chazal (Kethuvoth 111a) say on the verse (Deuteronomy 4:9): "And you that did cleave to the L-rd your G-d are all alive this day." Now is it possible for a man to cleave to the Shechinah? Is it not written (Ibid. 24): "For the L-rd your G-d is a consuming fire!" The intent is, rather, if one weds his daughter to a Torah scholar, or does business for a Torah scholar, or benefits a Torah scholar with his possessions, it is accounted to him as if he cleaved to the Shechinah." And they stated further (Ibid. 10b): "All who lodge Torah scholars in their homes and offer them of their fare are regarded by Scripture as presenters of daily ['continual'] sacrifices." And (Ibid. 63b): "R. Nechemiah opened [his discourse] in honor of the host, expounding (I Samuel 15:6): 'And Saul said to the Keni: Go, depart, go down from the midst of Amalek, lest I destroy you with him — and you have done lovingkindness with all the children of Israel': Now does this not follow a fortiori? If Yithro, who befriended Moses only for his own honor had this accorded [to his descendants, the Keni], then one who is host to a Torah scholar, and feeds him, and gives him to drink, and treats him of his possessions, how much more so!'… R. Elazar b. R. Yossi Haglili opened [his discourse] in honor of the host, expounding (II Samuel 6:11): 'And the L-rd blessed the house of Oved-Edom… because of the ark of G-d' [which he kept in his house]. Now does this not follow a fortiori? If the ark, which did not eat and did not drink — because they swept and sprinkled before it, thus [were they rewarded], then one who is host to a Torah scholar, and feeds him, and gives him to drink, and treats him of his possessions, how much more so!'"

This being so, let the foresighted reflect that if a person grows used to speaking with his mouth other than what is in his heart his children will undoubtedly stray and eventually deny the Torah, measure for measure. Moreover, he alienates himself from the holiness emanating from above and forfeits that distinction that is ascribed to Israel in the verse, “And as for you who cling to Hashem your God, you are all alive this day” (Devarim 4:4). To understand the significance of this verse consider that when a man tightens his belt until it clings tightly to his waste, not even dust can penetrate between the belt and the garment. So too, when Israel cling to Hashem through their meritorious ways and deeds, no accuser can intervene between them and their Heavenly Father. Take a look at what the Zohar (Parashas Pekudei 225a) writes on this topic:
