Acts 7:44

Stephen pointed out that it was the tabernacle of testimony in the wilderness that God had ordered built, not the temple. God even gave Moses blueprints to follow in constructing it because its design had instructive value. The tabernacle of testimony was important primarily because it contained God’s revealed will and it was the place that God’s presence dwelt in a localized sense. The "testimony" was the tablets of the Mosaic Law that rested in the ark of the covenant.
