There are Jews in Israel preparing for service in the rebuilt Jewish temple

A group of religious Jews who live in the Jordan Valley near the ancient city of Jericho are taking practical steps to prepare for the building of the third temple in Jerusalem by preparing descendants of the Kohanim, the priests, and the Levites for service in this next temple. These Jewish leaders have established a training center where temple priests can learn exactly how to conduct the daily temple services and offer the required sacrifices as dictated by the Jewish laws from the Biblical book of Leviticus.

The training center will include an exact replica of the temple where the student-priests can learn to do their duties which are required and this training center, the organizers believe, comes at an historic time marking the beginning of the work for the third temple.
