Commentaire sur Le Lévitique 26:1

לא תעשו לכם אלילם YE SHALL MAKE YOU NO IDOLS This command is repeated here with reference to one who has sold himself as a slave to a non-Jew in order that he should not say "Since my master is a libertine I will be like him; since my master worships idols, I will be like him; since my master desecrates the Sabbath, I will be like hin", on this account have these verses (v. 1 and v. 2) been stated. Indeed all these sections (these of the whole Sedrah) are stated in the sequence in which the incidents to which they refer actually occur. First Scripture warns the people about the seventh year's produce (not to do trade in them). If, however, one is covetous of money and brings himself under the constant suspicion of trading in the seventh-year fruits, he will at some time have to sell his movable property on account of his destitution. It is for this reason that Scripture put in juxtaposition to it (the“And when you make a sale [to your fellow-Jew]” (25:14) “or make a purchase from the hand…,” something that is transferred from hand to hand). If he still does not repent, he will eventually have to sell his inheritance (25:25). If he even then does not repent, he will eventually have to sell his home, and if even then, he does not repent, he will eventually have to borrow money with interest (verses 25:35-38). Now, the later the scenario in this passage, the more severe it is [i.e., first he sells his belongings, then his property, then his home and then even borrowing with interest which is more severe than selling one’s property; (Nachalath Ya’akov) thus, the passage continues accordingly, for] if he still does not repent, he will eventually have to sell himself [to his fellow Jew as a servant] (verses 25:39-46); and [finally,] if he has still not repented, not enough that he had to be sold to his fellow Jew - but he will [be forced to sell himself] even to a non-Jew! (Kiddushin 20a)

YE SHALL MAKE YOU NO IDOLS. “Scripture is speaking with reference to this person [mentioned above] who sold himself to an idolater, that he should not say, ‘Since my master worships idols, I will also worship them; Since my master is immoral, I too will be dissolute; since my master does not observe the Sabbath, I will also profane the Sabbath.’ Scripture therefore states, Ye shall make you no idols … Ye shall keep My Sabbaths, and reverence My Sanctuary.²²⁵Verses 1-2. Thus Scripture warned concerning [the observance of] the commandments.” This is the language of the Torath Kohanim,²²⁶Torath Kohanim, end of Behar. and the interpretation [thereof is as follows]: Scripture warned the servant who sold himself to an idolater to be heedful of the commandments concerning idolatry and the Sabbath, — as well as the reverence due to the Sanctuary, which he should come to on the festivals and treat with awe,²²⁷See “The Commandments,” Vol. I, pp. 29-31. and the same warning applies with regard to all the commandments. However, He mentioned only these commandments as they are the main ones, and they indicate [that the same principle applies] to all of them. Now some texts of the Torath Kohanim have this reading: “Scripture ‘mentioned here’ [the commandments,” instead of “Thus Scripture warned,” as stated above]. If this is the correct text, then the Rabbis [of the Torath Kohanim] alluded to [the concept] that all the commandments are included in the Sabbath and the Sanctuary. The person learned [in the mysteries of the Cabala] will understand.²²⁸See Ramban above in Seder Kedoshim 19:30.

לא תעשו לכם, even though you yourselves are now subservient to the pagans, as for instance the Jew who was forced to sell himself to a pagan, you must not trade your dignity, i.e. your religion, for a religion which is totally useless. Although this whole line appears superfluous, as the Torah had spoken on this subject repeatedly, the Torah here inserts this line so that people who due to force of circumstances had to enter the service of pagans, and who attribute this to their own G’d having abandoned them, do not commit the additional error of thinking that Judaism no longer has a claim on them in such circumstances. In Ezekiel chapter 20 the prophet dealt with the people who wanted to know how G’d could still have a claim on them seeing he had “sold” them to the pagans into exile. The matter was compared to a husband who had divorced his wife and continued to dictate to her. One of the most convincing answers is that G’d continues to speak of “My servant David” in Samuel II 3,18, the same description G’d applies to Nevuchadnezzar in Jeremiah 28,9. In other words, no human being whether out of his own volition or because he considers himself rejected by G’d, is ever free from the obligation to serve the Creator, His ultimate Master. At the end of the תוכחה, the predictions of the retribution we will experience for failure to observe G’d’s commandments, (Leviticus 26,44) G’d is on record as saying that even when the Jewish people have reached a historic low in their fortunes, G’d did not despise them nor abandon them permanently.
