Musar su Levitico 20:3

There are some [negative commandments] that are dependent upon the tongue, for which we give lashes. For so did our Rabbis, may their memory be blessed, say (Makkot 16a), “All the warnings in the Torah - we do not give lashes for a negative commandment that does not [involve] an action, except for one who makes an oath or curses his fellow with [God’s] name.” And even though there is no death penalty from the court with a vain oath, its punishment at the hands of the Heavens is more weighty than many sins that do have a death penalty from the court. For making an oath in vain profanes [God’s] name - as it is stated (Leviticus 19:12), “You shall not swear falsely by My name, profaning the name of your God” - and the punishment for profaning the name is more elevated than [that of] all of the sins. And it is not written like this about any of the sins besides a false oath and idolatry, as it is stated (Leviticus 20:3), “because he gave of his offspring to Molech and so defiled My sanctuary and profaned My holy name.” And it is stated in the warning about idolatry (Exodus 20:5), “You shall not bow down to them or serve them, for I the Lord, your God, am a jealous God.” [This] means to say, that He will not forgive the iniquity of idolatry in the way of forgiveness for other sins - like the matter that is written (Jeremiah 5:7), “Why should I forgive you; your children have forsaken Me and sworn by no-gods!” And likewise is it written in the warning for a false oath (Exodus 20:7), “for the Lord will not clear one who swears falsely by His name.” And the warning for a false oath is written (immediately) after the warning of idolatry, most certainly because the iniquity of profaning God, may He be blessed, is found under the wings of a false oath. And our Rabbis, may their memory be blessed, said regarding the matter of the verse (Proverbs 30:8-9), “Give me neither poverty nor riches, etc. Lest, being sated, I renounce, saying, ‘Who is the Lord,’ or, being impoverished (it is written fully with an aleph, but its meaning is, poor), I take to theft, and profane the name of my God,” that the latter is harsher than the former - as it is stated (Ezekiel 20:39), “As for you, O House of Israel, etc., go, every one of you, and worship his idols and continue, if you will not obey Me; but do not profane My holy name any more.” It is meaning to say that the iniquity of the one who swears falsely in a court is more weighty than the punishment of one who worships idolatry in private, due to the profaning of the name [involved in the former]. And our Rabbis, may their memory be blessed, said (Shevuot 39a), “For all of the other transgressions in the Torah, punishment is exacted only from the transgressor and his family; whereas here, punishment is exacted from him and from the entire world,” And if the court obligates a man to make an oath but he knows that his mouth speaks falsely (it would be a false oath), it is forbidden to [even] take the oath upon himself, saying, “I will swear” - in order to frighten his fellow - even though he does not plan to swear. For it is stated, (Exodus 20:7), “You shall not bear” - and included in its meaning is not to accept (agree) to swear falsely. And likewise did they, may their memory be blessed, say in our Mekhilta (Mekhilta d’Rabbi Yishmael, Yitro). And the Targum (translation of Onkelos) of, “Do not bear a vain report“ (Exodus 23:1), is “do not accept.” And it is forbidden to make a needless oath, even if he is swearing about the truth, as it is stated (Exodus 20:7), “Do not bear the name of God in vain” - and its Targum is, “for nothing.” And likewise is the iniquity of one who causes his fellow to swear for nothing, great - for example when his fellow owed him a hundred and he doubled it in his claim, in order that the law would come out that one who admits partially is obligated to make a Torah-based oath; or when he claims against his fellow for nothing and asks him for what he knows nothing about and makes him take a [rabbinic] oath of inducement. And our Rabbis said (Shevuot 39a) that this man is called a thief, as he is stealing his mind (deceiving him); and about him is it stated (Zechariah 5:4), “[But] I have sent it forth - declares the Lord of Hosts - and [the curse] shall enter the house of the thief and the house of the one who swears falsely by My name, and it shall lodge inside their houses and shall consume them to the last timber and stone.” And one who knows that if he takes an oath, people will suspect him about [the truth of] the oath, should restrain himself from [taking] the oath for the honor of the Heavens - even though the truth is with him.

לא תגנובו, "Do not steal," alludes to Adam who was a thief. נטע רבעי, the legislation of sanctifying the fruit of a tree in its fourth year, alludes to Noach who was drunk on a Wednesday. When a stranger (convert to Judaism) takes up residence among you, etc.," is an allusion to the first convert, Abraham. The prohibition of offering one's children as a sacrifice to the Moloch (20,2) is not part of the general prohibition to worship idols, but concerns itself specifically with the worship of fire. There are two kinds of fire. There is the fire described by the prophet Ovadiah 1,18 in the words: והיה בית יעקב אש, "The house of Jacob will turn into fire." This is a sacred fire, because the Lord your G–d is also called "fire." Also the fire in the Temple (Deut. 4,24) was sacred fire. However, there is another kind of fire, the fire of Esau, the fire of purgatory, a destructive fire emanating from the קליפה. When discussing the Moloch, the Torah adds (20,3) למען טמא את מקדשי ולחלל את שם קדשי, "and he so defiled My Temple and profaned My holy Name." How does the Temple feature in this paragraph? What does a fire-offering to the Moloch have to do with the Temple? The Torah wishes to point out that though fire-offerings to the Moloch are an abomination, there are fire- offerings such as the ones brought by Jacob which reflect the highest level of sanctity. When the Torah writes: והתקדשתם והייתם קדושים, it is an instruction to sanctify את קדוש יעקב, the G–d considered as the personification of holiness by Jacob. This is merely another way of saying: קודש ישראל לה', or that His name is called ישראל, the concept known as ישראל סבא, the first manifestation of G–d when He commenced creating the universe as a יש מאין by means of the first נקודה, as we explained above.
