1 And take thou unto thee Aaron thy brother, and his sons with him, from among the children of Israel, that he may minister unto me in the priest’s office, even Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron’s sons.

We now turn from the details of the tabernacle structure to the dress and preparation of the priests that would carry out its duties. First of all, there were specific men appointed to the office of the priest. At this point it was to be Aaron and his sons. In all, there were only five of them, and we heard previously that there were 600,000 men who participated in the Exodus. If that means 600,000 households, and all of them were only to make a single offering in a year, then it would be approximately 329 households serviced per priest every day of the year.

Of course, eventually the priesthood would be expanded to the entire tribe of Levi, but even then, there is an even smaller bottleneck when we consider that there was only one altar in the tabernacle courtyard upon which to sacrifice animals. According to the numbers that we have, that one altar would have to facilitate 1,644 sacrifices per day for each household to make one offering per year.

And we have not even addressed special times of the year, such as the festivals, when everyone would be bringing an offering at once! In short, I don’t know how the logistics of sacrifices at the tabernacle worked. I don’t think we have all enough details to understand how the work was distributed so that every Israelite could make an offering when he needed to.

But presumably there was a robust enough system that it did work, and there were dedicated men whose whole labor would be carrying out these most sacred rituals, connecting every individual soul in Israel to God.
