A manual transmission is the more hands-on way of driving. The driver controls how the engine’s power gets to the wheels by using a gear stick and a clutch pedal. The clutch temporarily disconnects the engine from the wheels, allowing the driver to change gears smoothly. Lower gears provide more power for starting or climbing hills, while higher gears allow the car to travel faster with less effort from the engine. It takes some coordination to learn, but it gives the driver more direct control over the car’s performance and can feel more engaging.
An automatic transmission does most of that work for you. Instead of a clutch pedal and manual gear changes, the car uses a system of sensors, hydraulics, and computers to decide when to shift gears based on speed and acceleration. The driver simply selects “drive” and uses the accelerator and brake. This makes driving easier, especially in stop-and-go traffic, because there’s less to think about. While it offers less direct control than a manual, modern automatics are very efficient and smooth.
Seen through this lens, the distinction between manual and automatic transmission becomes a useful bridge into the question of agency in the sacrificial system described in the Book of Leviticus in general and in this week’s Torah reading of Tzav in particular (Exodus 6-8). A manual transmission demands that the driver actively perform each step, engaging directly in every shift and adjustment, while an automatic allows the driver to set direction and intent, leaving the intricate execution to a responsive system. In a similar way, the individual bringing an offering did not operate in a purely “manual” mode of performing every detail himself, nor was the process entirely detached from him. Instead, through the agency of the Kohen, his intention was carried forward into precise, disciplined action, creating a model that blends personal initiation with delegated expertise.
Last week’s reading of Vayikra and this week’s reading of Tzav stand side by side, describing many of the same offerings, yet from distinctly different vantage points. Vayikra is oriented toward the individual who brings the sacrifice, focusing on what is brought, when it is required, and the responsibility that rests on the person initiating the offering. Tzav, by contrast, revisits these same acts but shifts the perspective inward, to the domain of the Kohen. Here, the emphasis is on procedure, continuity, and execution, detailing how each offering is handled, maintained, and completed once it enters the Kohen’s sphere, transforming the act from obligation into sustained service.
The reading of Tzav opens with God speaking to Moses, instructing him to command Aaron and his sons regarding the Olah, the burnt offering. The scene is set at the altar, where the fire must burn continuously through the night. The offering remains on the altar until morning, and the Kohen rises early to tend to it. He puts on his linen garments, lifts the ashes from the altar, and places them beside it. Then he changes into different garments and carries the ashes outside the camp to a designated pure place. The fire on the altar is kept constantly burning, never extinguished, and fresh wood is arranged on it each morning as the burnt offering is placed upon it and the fats of the peace offerings are burned.
The focus then shifts to the grain offering. Aaron and his sons are instructed to bring it before the altar. A handful of fine flour mixed with oil and all the frankincense is taken as a memorial portion and burned on the altar, creating a pleasing aroma. The remainder belongs to Aaron and his sons and is eaten as unleavened bread within the courtyard of the Tent of Meeting. It is described as most holy, like the sin offering and the guilt offering. Only males among the Kohens may eat it.
A new scene describes the daily offering of Aaron and his sons, brought on the day of anointing and thereafter each day. It consists of a fixed measure of fine flour, half offered in the morning and half in the evening. It is prepared with oil on a griddle, brought well-mixed, and entirely burned on the altar. Unlike other grain offerings, it is not eaten but completely offered up.
The narrative then turns to the sin offering. God instructs Moses to tell Aaron and his sons that the sin offering is to be slaughtered in the same place as the burnt offering, before God, and is most holy. The Kohen who offers it eats it in a holy place. Any garment that is splashed with its blood must be washed in a holy place. Earthen vessels in which it is cooked must be broken, while copper vessels must be scoured and rinsed. Any male among the Kohens may eat it, but if its blood is brought into the Tent of Meeting for atonement, it must not be eaten and is instead burned with fire.
The scene shifts again as instructions are given for the guilt offering. It is slaughtered in the same place as the burnt offering, and its blood is dashed against the altar. Its fat portions are burned, while the flesh belongs to the Kohens and is eaten in a holy place. Like the sin offering, it is most holy.
The narrative broadens to summarize the law of the offerings: the burnt offering, the grain offering, the sin offering, the guilt offering, the ordination offering, and the peace offering. These are presented as the instructions given by God to Moses on Mount Sinai, on the day the Israelites were commanded to bring their offerings in the wilderness.
The final scenes describe the peace offering in more detail. If it is brought as a thanksgiving offering, it is accompanied by unleavened cakes mixed with oil, wafers spread with oil, and cakes of fine flour well mixed with oil, along with loaves of leavened bread. One portion from each is given to the Kohen as a contribution. The flesh of the thanksgiving offering must be eaten on the same day it is offered, leaving none until morning (this basically made you invite a lot of people for what in essence becomes a festive meal). If the offering is a vow or a freewill offering, it may be eaten on the day of sacrifice and the next day, but anything left until the third day must be burned. Eating it on the third day invalidates the offering.
The next section deals with rules about purity. Meat that touches anything unclean may not be eaten and must be burned. Only those who are pure may eat the meat of peace offerings. Anyone who eats while in a state of impurity is cut off from the people. The prohibition against consuming fat and blood is emphasized, applying to all generations wherever the Israelites live. The blood is never to be eaten, and anyone who does so is cut off.
The final sequence shifts from laws of offerings to the consecration of Aaron and his sons. Moses is instructed to assemble the entire community at the entrance of the Tent of Meeting. Aaron and his sons are brought forward, and Moses washes them with water. He then dresses Aaron in the priestly garments, placing the tunic, sash, robe, ephod, breastpiece, and turban upon him, and sets the metal headband on his forehead. The anointing oil is poured upon Aaron’s head, consecrating him. Moses also anoints the Tabernacle and all its vessels, sprinkling the oil and sanctifying the altar seven times. Aaron’s sons are then dressed in their tunics, sashes, and headgear.
The offerings for the consecration follow. A bull is brought as a sin offering, and Aaron and his sons lay their hands upon its head before it is slaughtered. Moses applies its blood to the altar, and the prescribed portions are burned, while the rest is burned outside the camp. A ram is then brought as a burnt offering, and again Aaron and his sons lay their hands upon it before it is slaughtered and entirely burned on the altar. A second ram, the ram of consecration, is brought, and Moses places some of its blood on the right ear, right thumb, and right big toe of Aaron and his sons. The fats and selected portions, along with unleavened bread, are placed in their hands and waved before God, then burned on the altar. Moses takes the breast as his portion.
The consecration continues with the sprinkling of the anointing oil and blood upon Aaron, his garments, and his sons, sanctifying them and their garments together. The flesh of the ram is cooked, and Aaron and his sons eat it at the entrance of the Tent of Meeting together with the bread from the basket of consecration. They are instructed not to leave the entrance for seven days, the full period of their ordination, repeating the process each day as commanded. The narrative closes with Aaron and his sons carrying out all that God commanded through Moses, remaining at the entrance of the Tent of Meeting for seven days, completing their consecration.
The next reading (which we only read in two weeks, because of Passover) deals with the eighth and final day of the consecration of Aaron, his sons and the Tabernacle. It is both a dramatic and tragic event as we’ll see then.
