Mereka harus kudus bagi Allah mereka dan tidak boleh mencemarkan nama Allah mereka, sebab merekalah yang mempersembahkan kurban-kurban api bagi Yang Mahakekal, roti Allah mereka; karena itu mereka harus kudus.
Ramban
YE ARE THE CHILDREN OF THE ETERNAL YOUR G-D: YE SHALL NOT CUT YOURSELVES, NOR MAKE ANY BALDNESS BETWEEN YOUR EYES FOR THE DEAD. This also is an explanatory commandment of what He said in the Torah with reference to the priests, They shall not make baldness upon their head etc., nor make any cuttings in their flesh,192Leviticus 21:5. and now he [Moses] will explain that it is not merely because of the distinction of the priests which He mentioned there, They shall be holy unto their G-d,193Ibid., Verse 6. that they were thus commanded. Rather, all the congregation are holy, every one of them,194Numbers 16:3. and all of you are the children of the Eternal your G-d like the priests; if so, you too, take heed to yourselves regarding this commandment like them. This explanation is in accordance with the opinion of our Rabbis195Yebamoth 13b. that both verses [the one here and the one in Leviticus] relate only to the practice [of cutting and making baldness as signs of mourning] for the dead, [although “the dead” is not mentioned in the priestly injunction in Leviticus]. But it is possible that the first commandment [in Leviticus was stated] in relation to priests to state that if the priest had his hair torn out and his flesh cut, he was not fit for the Divine Service, just as He said, and they shall not profane the Name of their G-d,193Ibid., Verse 6. and their Service is thus profaned [i.e., invalidated]. Here he explained that the commandment applies also to the Israelites, both prohibitions being necessary.196By combining both statements we deduce that the prohibition against making baldness relates to the whole head and not only between the eyes, that it relates to the practice in connection with mourning for the dead, and finally that a separate penalty is incurred for each incision into the flesh (Makkoth 20 a-b).
And Rashi wrote: “Because you are the children of the Eternal it is becoming for you to be comely and not be cut about and bald [due to the tearing out of hair].” But it is not correct, for if so this commandment should be binding even [if the deeds were done] not for the dead! And Rabbi Abraham ibn Ezra commented: “Once you realize that you are the children of the Eternal and that He loves you more than a father loves his child, you should not cut yourselves [in bereavement] for anything that He does, because whatever He has done is for your good although you may not understand it, just as little children do not understand their father, yet rely on him. For thou art a holy people,197Verse 2. and you are not like all the other nations; therefore you shall not do as they do.”
In my opinion the purport of the expression for thou art a holy people197Verse 2. [is to state] an assurance of the eternal existence of the souls before Him, blessed be He. The verse declares: “Since you are a holy people and the treasure of G-d — neither doth G-d respect any person, but He deviseth means that he that is banished be not an outcast from Him198II Samuel 14:14. — therefore it is improper for you to make incisions in your flesh and tear your hair for the dead even if he perisheth in youth.199Job 36:14. Scripture, however, did not prohibit weeping for the dead since it is natural to cry when parting from beloved ones, and when they go on a journey even in life. From this verse, there is support for our Rabbis in prohibiting excessive mourning for the dead.200Moed Katan 27b.

Rabbeinu Bahya
Nachmanides comments on Exodus 32,27 where Moses tells the Levites to seek out the idolaters who served the golden calf and to execute them that the words אלו-הי ישראל in that verse refer to the attribute to whom sacrificial service to G’d is directed. Furthermore you find a verse in Chronicles II 29,7 ועולה לא העלו בקדש לאלו-הי ישראל, “they did not offer burnt offerings in the holy place to the G’d of Israel.” This teaches clearly that such burnt offerings were offered to the attribute known as אלו-הי ישראל. Another explicit verse teaching us the same is found in Leviticus 21,8: כי את לחם אלו-היך הוא מקריב, “for he offers the food of your G’d,” and the attribute אלו-הים is used to describe the attribute of G’d to whom the offerings are directed.
Additionally, it is worthwhile to reflect on the expression לחם אשה, in Leviticus 3,11 where the priest is described as the one offering such an offering to Hashem. The word אשה is derived from אש; we have many similar expressions all referring to certain sacrifices as אשה לה’, “fire-offerings to the Lord.” The reason that the Torah does not describe such food for the altar as (לחם אש) “fiery food,” is that the word אשה is almost identical to the word אשה, woman, meaning that the recipient of the sacrifice is passive like a woman who is passive, a recipient. All of this proves that sacrifices are offered to the attribute of Justice. This is the reason that such “food,” i.e. לחם, is called לחם אשה.
The truth is that while the sacrifices are offered up to the attribute אלו-הים, they are intended for the attribute Hashem. Similarly, when we offer our prayers in (lieu of sacrifices), we dedicate them to the attribute which is far above all our abilities to praise, and we verbalize that when we emphasize this very fact by saying that G’d is מרומם על כל ברכה ותהלה “exalted far above every blessing and praise” (Nechemyah 9,5). The same thought is expressed in the Kaddish prayer i.e.לעילא מכל ברכתא ושירתא תושבחתא.

Rashi
קדשים תהיו YE SHALL BE HOLY — This means, keep aloof from the forbidden sexual relations just mentioned and from sinful thoughts. [It is evident that this is the meaning of קדשים תהיו because] wherever you find in the Torah a command to fence yourself in against such relations you also find mention of “holiness". Examples are: (Leviticus 21:7) “[They shall not take] a wife that is a harlot, or a profane etc.", and in the next verse "for I, the Lord, who sanctifieth you, [am holy]"; (Leviticus 21:15) “Neither shall he profane his seed (by the forbidden unions mentioned in the preceding verses) for I the Lord do sanctify him"; (Leviticus 21:6) "They shall be holy… followed by (v. 7) "[they shall not take] a wife that is a harlot or a profane" (cf. Vayikra Rabbah 24:4-6).
