וַיְדַבֵּ֤ר יְהוָה֙ אֶל־מֹשֶׁ֔ה אַחֲרֵ֣י מ֔וֹת שְׁנֵ֖י בְּנֵ֣י אַהֲרֹ֑ן בְּקָרְבָתָ֥ם לִפְנֵי־יְהוָ֖ה וַיָּמֻֽתוּ׃ וַיֹּ֨אמֶר יְהוָ֜ה אֶל־מֹשֶׁ֗ה דַּבֵּר֮ אֶל־אַהֲרֹ֣ן אָחִיךָ֒ וְאַל־יָבֹ֤א בְכָל־עֵת֙ אֶל־הַקֹּ֔דֶשׁ מִבֵּ֖ית לַפָּרֹ֑כֶת אֶל־פְּנֵ֨י הַכַּפֹּ֜רֶת אֲשֶׁ֤ר עַל־הָאָרֹן֙ וְלֹ֣א יָמ֔וּת כִּ֚י בֶּֽעָנָ֔ן אֵרָאֶ֖ה עַל־הַכַּפֹּֽרֶת׃
The LORD spoke to Moses after the death of the two sons of Aaron who died when they drew too close to the presence of the LORD. The LORD said to Moses: Tell your brother Aaron that he is not to come at will into the Shrine behind the curtain, in front of the cover that is upon the ark, lest he die; for I appear in the cloud over the cover.
כי בענן אראה. כִּי תָמִיד אֲנִי נִרְאֶה שָׁם עִם עַמּוּד עֲנָנִי, וּלְפִי שֶׁגִּלּוּי שְׁכִינָתִי שָׁם, יִזָּהֵר שֶׁלֹּא יַרְגִּיל לָבֹא, זֶהוּ פְשׁוּטוֹ; וּמִדְרָשׁוֹ: לֹא יָבֹא כִּי אִם בַּעֲנַן הַקְּטֹרֶת בְּיוֹם הַכִּפּוּרִים (יומא נ"ג):
כי בענן אראה means, for I constantly show Myself there with My pillar of cloud, and because the revelation of My Shechinah takes place there he should take care not to make it his habit to come there. This is the literal meaning of the verse. The Halachic explanation is: He shall not come into the Holy of Holies except with (i.e. on the occasion when he is going to raise) a cloud of incense on the Day of Atonement (Yoma 53a).

וְלָקַ֖ח אֶת־שְׁנֵ֣י הַשְּׂעִירִ֑ם וְהֶעֱמִ֤יד אֹתָם֙ לִפְנֵ֣י יְהוָ֔ה פֶּ֖תַח אֹ֥הֶל מוֹעֵֽד׃ וְנָתַ֧ן אַהֲרֹ֛ן עַל־שְׁנֵ֥י הַשְּׂעִירִ֖ם גּוֹרָל֑וֹת גּוֹרָ֤ל אֶחָד֙ לַיהוָ֔ה וְגוֹרָ֥ל אֶחָ֖ד לַעֲזָאזֵֽל׃ וְהִקְרִ֤יב אַהֲרֹן֙ אֶת־הַשָּׂעִ֔יר אֲשֶׁ֨ר עָלָ֥ה עָלָ֛יו הַגּוֹרָ֖ל לַיהוָ֑ה וְעָשָׂ֖הוּ חַטָּֽאת׃ וְהַשָּׂעִ֗יר אֲשֶׁר֩ עָלָ֨ה עָלָ֤יו הַגּוֹרָל֙ לַעֲזָאזֵ֔ל יָֽעֳמַד־חַ֛י לִפְנֵ֥י יְהוָ֖ה לְכַפֵּ֣ר עָלָ֑יו לְשַׁלַּ֥ח אֹת֛וֹ לַעֲזָאזֵ֖ל הַמִּדְבָּֽרָה׃
Aaron shall take the two he-goats and let them stand before the LORD at the entrance of the Tent of Meeting; and he shall place lots upon the two goats, one marked for the LORD and the other marked for Azazel. Aaron shall bring forward the goat designated by lot for the LORD, which he is to offer as a sin offering; while the goat designated by lot for Azazel shall be left standing alive before the LORD, to make expiation with it and to send it off to the wilderness for Azazel.
עזאזל. הוּא הַר עַז וְקָשֶׁה, צוּק גָּבוֹהַּ, שֶׁנֶּאֱמַר אֶרֶץ גְזֵרָה — חֲתוּכָה:
עזאזל AZAZEL — (The word is taken to be a compound of עזז "to be strong" and אל "mighty"). Talmud, Yoma 67b.
When he has finished purging the Shrine, the Tent of Meeting, and the altar, the live goat shall be brought forward. Aaron shall lay both his hands upon the head of the live goat and confess over it all the iniquities and transgressions of the Israelites, whatever their sins, putting them on the head of the goat; and it shall be sent off to the wilderness through a designated man. Thus the goat shall carry on it all their iniquities to an inaccessible region; and the goat shall be set free in the wilderness. And Aaron shall go into the Tent of Meeting, take off the linen vestments that he put on when he entered the Shrine, and leave them there. He shall bathe his body in water in the holy precinct and put on his vestments; then he shall come out and offer his burnt offering and the burnt offering of the people, making expiation for himself and for the people.
וְהָיְתָ֥ה לָכֶ֖ם לְחֻקַּ֣ת עוֹלָ֑ם בַּחֹ֣דֶשׁ הַ֠שְּׁבִיעִי בֶּֽעָשׂ֨וֹר לַחֹ֜דֶשׁ תְּעַנּ֣וּ אֶת־נַפְשֹֽׁתֵיכֶ֗ם וְכָל־מְלָאכָה֙ לֹ֣א תַעֲשׂ֔וּ הָֽאֶזְרָ֔ח וְהַגֵּ֖ר הַגָּ֥ר בְּתוֹכְכֶֽם׃ כִּֽי־בַיּ֥וֹם הַזֶּ֛ה יְכַפֵּ֥ר עֲלֵיכֶ֖ם לְטַהֵ֣ר אֶתְכֶ֑ם מִכֹּל֙ חַטֹּ֣אתֵיכם לִפְנֵ֥י יְהוָ֖ה תִּטְהָֽרוּ׃ שַׁבַּ֨ת שַׁבָּת֥וֹן הִיא֙ לָכֶ֔ם וְעִנִּיתֶ֖ם אֶת־נַפְשֹׁתֵיכֶ֑ם חֻקַּ֖ת עוֹלָֽם׃
And this shall be to you a law for all time: In the seventh month, on the tenth day of the month, you shall practice self-denial; and you shall do no manner of work, neither the citizen nor the alien who resides among you. For on this day atonement shall be made for you to cleanse you of all your sins; you shall be clean before the LORD. It shall be a sabbath of complete rest** for you, and you shall practice self-denial; it is a law for all time.
וְהָֽיְתָה־זֹּ֨את לָכֶ֜ם לְחֻקַּ֣ת עוֹלָ֗ם לְכַפֵּ֞ר עַל־בְּנֵ֤י יִשְׂרָאֵל֙ מִכָּל־חַטֹּאתָ֔ם אַחַ֖ת בַּשָּׁנָ֑ה וַיַּ֕עַשׂ כַּאֲשֶׁ֛ר צִוָּ֥ה יְהוָ֖ה אֶת־מֹשֶֽׁה׃ (פ)
This shall be to you a law for all time: to make atonement for the Israelites for all their sins once a year. And Moses did as the LORD had commanded him.
What is the connection between Shabbat and Shabbat Shabbaton? [The Hebrew root word, Sh-V שב]
How do we grasp the idea of Holiness?
(מה) כִּ֣י ׀ אֲנִ֣י ה' הַֽמַּעֲלֶ֤ה אֶתְכֶם֙ מֵאֶ֣רֶץ מִצְרַ֔יִם לִהְיֹ֥ת לָכֶ֖ם לֵאלֹקִ֑ים וִהְיִיתֶ֣ם קְדֹשִׁ֔ים כִּ֥י קָד֖וֹשׁ אָֽנִי׃
(45) For I am God, the One who brings you up from the land of Egypt to be your God; and you shall be holy, for I am holy.
וְהִ֨תְקַדִּשְׁתֶּ֔ם וִהְיִיתֶ֖ם קְדֹשִׁ֑ים כִּ֛י אֲנִ֥י יְהוָ֖ה אֱלֹהֵיכֶֽם׃
What does it mean to be Holy? Our Sages Weigh In.....
הפרישות היא תחלת החסידות. ותראה שכל מה שביארנו עד עתה הוא מה שמצטרך אל האדם לשיהיה צדיק ומכאן ולהלאה הוא לשיהיה חסיד.
Separation is the beginning of Piety.
וַיֹּ֣אמֶר אֱלֹהִ֗ים יְהִ֤י מְאֹרֹת֙ בִּרְקִ֣יעַ הַשָּׁמַ֔יִם לְהַבְדִּ֕יל בֵּ֥ין הַיּ֖וֹם וּבֵ֣ין הַלָּ֑יְלָה וְהָי֤וּ לְאֹתֹת֙ וּלְמ֣וֹעֲדִ֔ים וּלְיָמִ֖ים וְשָׁנִֽים׃
God said, “Let there be lights in the expanse of the sky to separate day from night; they shall serve as signs for the set times—the days and the years;
בְּכָל דְּבָרֶיךָ וּמַעֲשֶֹיךָ וּמַחְשְׁבוֹתֶיךָ, וּבְכָל עֵת – חֲשׁוֹב בְּלִבָּךְ כְּאִלוּ אַתָּה עוֹמֵד לִפְנֵי הַקָּדוֹשׁ בָּרוּךְ הוּא וּשְׁכִינָתוֹ עָלֶיךָ, כִּי כְּבוֹדוֹ מָלֵא הָעוֹלָם. וּדְבָרֶיךָ יִהְיוּ בְּאֵימָה וּבְיִרְאָה, כְּעֶבֶד לִפְנֵי רַבּוֹ.
In all your actions, words and thoughts, always regard yourself as standing before God, with His Shechinah (Divine Presence) above you, for His glory fills the whole world. Speak with fear and awe, as a servant in the presence of his master.
Genuine holiness is the altruistic striving for good for its own sake, not out of self-interest.
Rav Kook, Ein Eyah vol. I, p. 104
כי יש שיטרחו מאד במחקר הבריאה והטבע, ואחרים יתנו כל עיונם לתכונה ולהנדסה, ואחרים למלאכות. ואחרים יכנסו יותר אל הקדש, דהיינו, למוד התורה הקדושה. מהם בפלפולי ההלכות, מהם במדרשים, מהם בפסקי הדינים.
There are those who toil greatly in studying the creation and nature. Others devote all their study to astronomy and mathematics, or to the arts. There are others which enter closer towards the sacred, namely, the study of the holy Torah....
ואף על פי שכבר קבועים בלב כל האדם הישר התחלותיו ויסודותיו, אם לא יעסוק בהם, יראה פרטיו ולא יכירם, יעבור עליהם ולא ירגיש בם
Although the beginnings and foundations of [piety] are already implanted in every upright person's heart, nevertheless if he does not engage himself in their study, he will encounter its branches but won't recognize them and he will tread over them without perceiving that he is doing so.
Sacred and Profane
וַיְבָ֤רֶךְ אֱלֹהִים֙ אֶת־י֣וֹם הַשְּׁבִיעִ֔י וַיְקַדֵּ֖שׁ אֹת֑וֹ כִּ֣י ב֤וֹ שָׁבַת֙ מִכָּל־מְלַאכְתּ֔וֹ אֲשֶׁר־בָּרָ֥א אֱלֹהִ֖ים לַעֲשֽׂוֹת׃
And God blessed the seventh day and declared it holy, because on it God ceased from all the work of creation that He had done.
וּֽלֲהַבְדִּ֔יל בֵּ֥ין הַקֹּ֖דֶשׁ וּבֵ֣ין הַחֹ֑ל וּבֵ֥ין הַטָּמֵ֖א וּבֵ֥ין הַטָּהֽוֹר׃
for you must distinguish between the sacred and the profane, and between the unclean and the clean;
כְּמַעֲשֵׂ֧ה אֶֽרֶץ־מִצְרַ֛יִם אֲשֶׁ֥ר יְשַׁבְתֶּם־בָּ֖הּ לֹ֣א תַעֲשׂ֑וּ וּכְמַעֲשֵׂ֣ה אֶֽרֶץ־כְּנַ֡עַן אֲשֶׁ֣ר אֲנִי֩ מֵבִ֨יא אֶתְכֶ֥ם שָׁ֙מָּה֙ לֹ֣א תַעֲשׂ֔וּ וּבְחֻקֹּתֵיהֶ֖ם לֹ֥א תֵלֵֽכוּ׃ אֶת־מִשְׁפָּטַ֧י תַּעֲשׂ֛וּ וְאֶת־חֻקֹּתַ֥י תִּשְׁמְר֖וּ לָלֶ֣כֶת בָּהֶ֑ם אֲנִ֖י יְהוָ֥ה אֱלֹהֵיכֶֽם׃ וּשְׁמַרְתֶּ֤ם אֶת־חֻקֹּתַי֙ וְאֶת־מִשְׁפָּטַ֔י אֲשֶׁ֨ר יַעֲשֶׂ֥ה אֹתָ֛ם הָאָדָ֖ם וָחַ֣י בָּהֶ֑ם אֲנִ֖י יְהוָֽה׃ (ס) אִ֥ישׁ אִישׁ֙ אֶל־כָּל־שְׁאֵ֣ר בְּשָׂר֔וֹ לֹ֥א תִקְרְב֖וּ לְגַלּ֣וֹת עֶרְוָ֑ה אֲנִ֖י יְהוָֽה׃ (ס)
You shall not copy the practices of the land of Egypt where you dwelt, or of the land of Canaan to which I am taking you; nor shall you follow their laws. My rules alone shall you observe, and faithfully follow My laws: I the LORD am your God. You shall keep My laws and My rules, by the pursuit of which man shall live: I am the LORD. None of you shall come near anyone of his own flesh to uncover nakedness: I am the LORD.
(ל) וְאַנְשֵׁי־קֹ֖דֶשׁ תִּהְי֣וּן לִ֑י וּבָשָׂ֨ר בַּשָּׂדֶ֤ה טְרֵפָה֙ לֹ֣א תֹאכֵ֔לוּ לַכֶּ֖לֶב תַּשְׁלִכ֥וּן אֹתֽוֹ׃ (ס)
(30) You should be holy people to Me: you must not eat meat torn apart by wild animals in the field; you shall throw that meat to the dogs.
For the life of the flesh is in the blood, and I have assigned it to you for making expiation for your lives upon the altar; it is the blood, as life, that effects expiation. Therefore I say to the Israelite people: No person among you shall partake of blood, nor shall the stranger who resides among you partake of blood.
Small sampling of representative laws from "The Holiness Code"
(10) If a man commits adultery with a married woman, committing adultery with another man’s wife, the adulterer and the adulteress shall be put to death. (11) If a man lies with his father’s wife, it is the nakedness of his father that he has uncovered; the two shall be put to death—their bloodguilt is upon them. (12) If a man lies with his daughter-in-law, both of them shall be put to death; they have committed incest—their bloodguilt is upon them. (13) If a man lies with a male as one lies with a woman, the two of them have done an abhorrent thing; they shall be put to death—their bloodguilt is upon them. (14) If a man marries a woman and her mother, it is depravity; both he and they shall be put to the fire, that there be no depravity among you.
