Moses becomes aware that one of the sin offerings had been burnt, rather than eaten. When he expresses his displeasure, Aaron explains his reasoning for ordering the burning of that particular offering, and Moses humbly accepts Aaron's explanation.

At this point, a heavenly fire descends and consumes the offerings on the altar. Aaron's eldest two sons, Nadab and Avihu, bring an unauthorized incense offering and a heavenly fire consumes them. Moses orders the removal of their bodies from the Tabernacle and instructs Aaron and his remaining two sons not to observe the traditional laws of mourning, considering that they had to continue serving in the Sanctuary on behalf of the Jewish nation. The priests are instructed not to imbibe wine before performing Temple service.

After concluding the offering of all the sacrifices, Aaron blesses the people with the priestly blessing. Moses and Aaron bless the Jewish people that G‑d's presence dwell in their handiwork, and, indeed, the Divine presence visibly descends upon the Tabernacle.

Moses gathers all the Jews to the Tabernacle to witness the Divine presence descending upon the Sanctuary on that day. Aaron offers various sacrifices in preparation for this revelation.

Moses sacrifices a second ram, and their fats are burnt on the altar, along with some breads.

We read yesterday about the induction of the priests and the inauguration of the Tabernacle. In the presence of all the Jews, Moses dressed Aaron and his sons in the priestly vestments and anointed them, along with the Tabernacle and its vessels, with the holy anointing oil.

Today, the priestly induction continues with Moses sacrificing a bullock and a ram as burnt offerings.

The Torah now discusses the Thanksgiving Offering, brought by an individual who survived a perilous circumstance. We then learn about various grounds for the invalidation of a sacrifice, such as impurity or improper thoughts on the part of the priest performing the service. We are then commanded not to consume blood or any of the fats offered on the altar. The prohibition against eating these fats applies to all domesticated animals. The section wraps up with the portions of meat the priest is given from the Peace Offering. With this we conclude the laws of sacrifices.

This section discusses the priestly meal offering, brought by the High Priest twice daily, and by every priest on the day he is first inducted into Temple service. The laws of the Sin Offering and Guilt Offering, also discussed in last week's reading, are also repeated with added details. An important principle discussed is a vessel's absorption of sacrificial meats cooked therein, and the possibility of purging (certain types of) vessels of the vestiges it absorbed — a concept which is very germane in the laws of kosher. This section concludes with a discussion regarding various gratuities the priests were entitled to take from the different offerings and sacrifices.

The Torah describes the mandatory daily removal of ashes from the altar. This was the first order of the day in the Temple service. The Torah then repeats the laws of the meal offerings described in last week's reading, adding several important details.

G‑d then teaches Moses the laws of the fowl Olah. This aliyah then continues with a description of three types of voluntary meal offerings: unbaked flour, baked loaves, and the shallow-fried meal offering. All voluntary meal offerings also contained olive oil and frankincense.
