Like the offerings, the annual festivals in the new temple were meant to purify the people and the land. Instead of the three main festivals of the time of Moses (the feasts of Passover, Harvest, and Tabernacles), there were now only two. These two, Passover and Tabernacles, were almost the same and took place six months apart.
The Passover festival still happened on the fourteenth day of the first month. It was similar to the earlier Passover in many ways, but it required many more sacrifices than those listed in Numbers 28. The Feast of Tabernacles is not directly named in the Hebrew text. It no longer had special customs or symbols, except that the prince offered the same sacrifices as he did for Passover. This festival still took place in the seventh month.
Throughout these descriptions, a main theme becomes clear: the land must be kept pure and free from sin.
