The passuk says צו את אהרן ואת בניו לאמר זאת תורת העלה היא העלה על מוקדה המזבח כל הלילה עד הבקר ואש המזבח תוקד בו.
Vayikra 6:2
One of the inyanim in this passuk is Hekter Chalavim v’eivarim, burning specific parts of the korban on the mizbe’ach. Hekter Chalavim v’eivarim is not exclusively for Korban Olah -it applies to other korbanos as well. So why is the passuk raising this topic specifically by korban Olah, which is mashma something about Olah is shoreshdik to Hekter Chalavim.
Also, Chazal say the olah is mechaper for hirhur ha’lev. The fact that hirhur needs a kapparah at all is interesting, because l’ma’aseh it didn’t reach the level of chet. If it was a chet, you’d think we’d need a chatas. Yet here the prescription is an Olah. It’s needs biyur.
Another nekuda in the parsha of Olah is the Trumas Hadeshen, which had a neis occur unnecessarily. The deshen was removed from the Mikdash, but a small amount was left on the mizbe’ach and that small amount was nivla, absorbed into the mizbe’ach. This was considered a neis. But, it’s not clear what the purpose of the neis was. HKBH doesn’t make unnecessary miracles, so it needs hesber what was the point of it?
Back to Hekter Chalavim v’eivarim. Hekter Chalavim is done at night. This is unusual, because generally Avodah is done during the day. So why here do we grant an Avodah to be done at night?
We can really ask a larger question about the Avodah of Korbanos. We know in Torah, the night precedes the day – “Vayhi Erev, Vayhi Boker.” This applies almost universally in Torah. The exception is Kodshim, like we see in our parsha. By Kodshim we say, fakhert, the night is the end of the day. The Avodah of the day can be finished at night. Ha’lo davar hu.
We find another inyan of Avodah done at night. We say kriyas Shema twice a day. Kiryas Shema is kabbalos Ol Malchus Shomayim. What’s the point of being mekabel Ol Malchus Shomayim before you go to sleep? In the morning, it makes sense — a person wakes up, is about to get busy and engage with the world, and accepts Hashem’s Ol as he heads into his day. But at night, before sleep, what does it mean to accepts Ol Malchus Shomayim? What is a person actually doing or committing to?
To be masbir this, we need to understand a strange Machlokes in the Gemara. The gemara asks was the night created l’girsa, for learning, or l’shinsa, for sleeping? What a strange argument — is the gemara asking whether people should sleep? Of course people need to sleep! It can’t be there’s a tzad that a person shouldn’t sleep. It must be the gemara is looking for what is the form of avodas Hashem at night. But even then, is the gemara entertaining sleep as Avodah? I can hear if the gemara asked whether Layla is better used for learning or davening, because we’re comparing different types of Avodah. But sleep? What’s the hesber in this Machlokes?
So the pshat goes like this:
The world of shena, even from a tevadi'ke point of view, from a scientific point of view, is something that's very hard to really understand its tachlis. It’s not just resting like sittnig around. It’s a metzius of shena where there's a change in the person's consciousness. It's a pelle! We believe HaKadosh Baruch Hu created a person to do avodah, to accomplish things in the world. But, with shena, a person is not a bar avodah, he’s not even a bar da'as! A third of our lives goes to shena where there's no avodah?
The answer is, a person’s actions have a dual direction to them. On the one hand, a person’s actions is him producing and giving outward toward the world. But, there’s another direction – a person’s actions are supposed to make a roshem on the person. The person himself is supposed to receive some sort of feedback from the ma'aseh and it’s supposed to make an impression on the person.
Take a first responder caught in an earthquake. In the moment, he is running, helping, saving lives, completely focused. But when he finally sits down afterward and the silence settles in, that’s when it hits him. The experience sinks in.
We’ve sensed this ourselves: the doing and the absorbing don’t always happen at the same time. Chazal describe this as b’eidei d’tarid l’miflat, lo ba’i — something that is busy giving out cannot simultaneously take in.
It’s like a Mohel as a Bris. The significance of the moment — being machnis a child b’briso shel Avraham Avinu — is, and should, move him deeply. But in the moment of the milah itself, he needs to be focused entirely on the technical act — as precise and professional as possible. The Feeling and doing don’t fully coexist.
The Kotzker Rebbe once said something sharp about this. A chassid came to him excitedly: “Rebbe, last night God spoke to me in a dream!” The Rebbe dismissed it: “You think about God during the day — the dream means nothing.” The chassid pushed back: “But I’m so busy doing mitzvos all day, I have no time to think about God!” And there, said the Kotzker, was the real point. When you are in doing mode, genuine absorption cannot happen.
HKBH did not build human life as a single continuous arc of doing. He built it in two complementary phases — doing and absorbing. We usually focus on the first one, but the second part, absorbing, is critical to avodas ha’adam
Sleep is the second half of avodah. It is when the person stops outputting and enters receive mode. The experiences, the learning, the mitzvos of the day — they begin to seep in. They start to become part of who you actually are. The night was not created as downtime. It was created as the completion of the day. It’s the Avodah of Layla. Lo nivra Layla eleh l’shinsa.
This is Why the night follows the day in Avodah. By Briyas Ha’Olam, where HKBH is creating, His process starts at night and ends by day. But in our Avodah, it’s the opposite. L’mashal:
When a playwright writes a play, the inner meaning and intention (the pnimiyus) comes to him first, and only then does he express it outwardly in the actual written play. But for the audience, it works in reverse — they first encounter the external presentation (the play itself), and only gradually absorb its deeper meaning.
So too with Creation: God 'conceived' the world first, His inner intention is hidden in darkness, Vayhi Erev, and then expressed outwardly in the light of boker. That is why in the calendar — which reflects God's act of creation — night comes first. We are marking His sequence.
But in human avodah, we work the other way, like the audience: first comes the action, the daytime service, and then comes the absorption in the nighttime, when we internalize what was done. That’s why in the Mikdash, with Avodas Adam, the night follows the day because it represents the second half of our avodah — the absorption phase.
This explains the Neis of Havla’as Hadeshen. The miracle was not arbitrary — it was the fulfillment of the avodah itself. The entire point of the nighttime phase is absorption. The havla’a into the mizbe’ach is refelctive of what the night's avodah is.
This is also why the Olah addresses hirhurei halev: The real reason a person has unwanted thoughts, even while doing everything right, is not that he is bad. It is that his goodness has not yet been fully absorbed into his bones. On one level you may know something to be wrong, but if it hasn’t seeped in, it’ll still arise in your hirhurim.
Hirhur halev is not a remedied with a chatas but davka an olah: a korban that is entirely consumed, totally absorbed, nothing left over. The olah is the korban of complete internalization.
This is obviously not just a Mizbe’ach concept. It is noge’ah us in many ways.
We spend enormous energy on the first half of avodah — the doing. Learning Torah, keeping mitzvos, being careful, being diligent. And that is right and essential. But most of us spend almost no time on the second half: letting it sink in.
There is an entire dimension of avodah called Chovos HaLevavos — Ahavas Hashem, Yiras Hasehm, and so on. The mistake people make is thinking that by doing mitzvos diligently and carefully, this inner world will automatically develop. It will not. You can force yourself to do the right actions. You can be meticulous in every mitzvah. But your thoughts and feelings will not automatically align with your actions unless you dedicate specific time to working on this inner dimension. Even learning the reasons behind Ahavas & Yiras Hashem — whether it’s six arguments, or nine or twelve — does not do it. You can tell when someone is reciting things he knows he ought to feel, versus someone who actually feels them.
Rav Yisrael Salanter understood that the real work of mussar is reaching the subconscious. You cannot assault the subconscious directly — by definition, whatever you’re actively attacking is already conscious. So how do you reach it?
The same way water soaks into the ground. You don’t force it. You leave it there. You keep something on your mind, mull it over, return to it, and — crucially — you sleep on it. You go to sleep with it still sitting in your thoughts, and something happens in the night that the daytime cannot accomplish. The Arizal says that the night holds secrets the day cannot reach. On the simplest level, this means that the deeper layers of a person open up only in stillness and receptivity — in the mode that night represents.
That is what Rav Yisrael Salanter meant when he said to learn mussar b’sefasayim dolkos. Saying the same line again and again with real emotional intensity. Not to learn new information — the Ramchal opens Mesilas Yesharim by saying: “I am not here to teach you anything you don’t already know.” The goal is to take what is already in your head and burn it downward, into your bones, until it becomes simply who you are.
We need to capitalize on the Avodah of Layla. There’s an Avodah of Shayna. There’s a kabbolas Ol Malchus Shomayim of the Layla davka. It’s the quietude needed for reflection, and absorption, which keep our flames going. We need to allow ourselves to catch fire and keep our fire buring – מוקדה המזבח כל הלילה – Lo sichbeh!
Good Shabbos!
