Altars in the Hebrew Bible were typically made of earth or unwrought stone. Altars were generally erected in conspicuous places. The first time the word altar is mentioned and recorded in the Hebrew Bible is that it was erected by Noah, although it does not specify that there was an altar in. Other altars were erected by Abraham, by Isaac, by Jacob, by Moses, and by Saul.

According to the Hebrew Bible, the tabernacle, also known as the Tent of the Congregation, was the portable earthly dwelling used by the Israelites from the Exodus until the conquest of Canaan. Moses was instructed at Mount Sinai to construct and transport the tabernacle with the Israelites on their journey through the wilderness and their subsequent conquest of the Promised Land. After 440 years, Solomon's Temple in Jerusalem superseded it as the dwelling-place of God.
