That is typical of what God requires on every one of the festivals except for one thing—the number of sacrifices required. The Feast of Tabernacles is a type, a symbol, of the Millennium, of the rule of God on earth. What we see here is a requirement to give offerings during the Feast of Tabernacles. What is so interesting is that the Feast of Tabernacles requires more sacrifices than all the other holy days combined! Far more! There were 172 animals sacrificed during those seven days.
Since the Feast of Tabernacles represents the Millennium, and the priest stands for us, and his major responsibility is to make offerings on behalf of the people before God, does that not picture how big our responsibility will be during the Millennium? There will be more sacrifices, more priestly work for us during that time than at any other period in God's plan.
Physically, the Levitical priests offered animals. In the Millennium, we will not be sacrificing animals. We need to understand what a priest does so that we understand sacrificing. A priest does a lot of it, and during the Millennium, there will be a need for a great deal of spiritual sacrificing.
