Designed by the Master Architect

Moshe was also given instructions for the exact design of the Mishkan by the Master Architect – HaShem!
The Mishkan would have 3 sections:
1. The Kodesh HaKadashim (Holy of Holies), where the ark containing the Ten Commandments would be kept.
2. The Kodesh (Holy), which contained the Shulchan (table), Menorah, and the Mizbei’ach HaZahav, the golden altar which was used to burn nice smelling spices.
3. The Chatzer (courtyard), where Bnei Yisrael could bring animal sacrifices on the big Mizbei’ach HaNechoshes (copper altar). Between this Mizbei’ach and the Kodesh was a huge pot, called the Kiyor, filled with water. The Kohanim would wash their hands and feet in the Kiyor before entering the Kodesh.
So keep in mind the 3 parts – the Kodesh HaKadashim, the Kodesh, and the Chatzer.
