Final answer:
The personal presence of God was primarily restored through the construction of the Tabernacle, where the Ark of the Covenant containing the Commandments resided, symbolizing God's presence with the Israelites in the wilderness.
Step-by-step explanation:
In the wilderness, after the Exodus, the personal presence of God was restored through the construction of the Tabernacle. This is exemplified by the events described in the Book of Exodus, where, under the leadership of Moses, the Israelites carried the Ark of the Covenant within the Tabernacle, a portable earthly dwelling place of God.
The Ark contained the stone tablets of the Ten Commandments, which were seen as a physical manifestation of God's presence and covenant with the Israelites. Additionally, other elements such as regular sacrifices and the leadership of Moses also played roles in maintaining a connection to God's presence, but it was the Tabernacle that primarily functioned as the focus for God's presence among the people during their travels in the desert.
