Albert Barnes Commentary Acts 7:44

"Our fathers had the tabernacle of the testimony in the wilderness, even as he appointed who spake unto Moses, that he should make it according to the figure that he had seen." — Acts 7:44 (ASV)

The tabernacle of witness. The tent or tabernacle that Moses was commanded to make. It was called a tabernacle of witness, or of testimony, because it was the visible witness or proof of God's presence with them; the evidence that the one to whom it was devoted was their protector and guide. The name is given either to the tent, or to the two tables of stone, or to the ark; all of which were witnesses or evidence of God's relation to them as their Lawgiver and Guide (Exodus 16:34; Exodus 25:16, 21; Exodus 27:21; Exodus 30:6, 36; Exodus 31:18).

Numbers 1:50, 53. The two charges against Stephen were that he had spoken blasphemy against Moses, or his law, and against the temple (Acts 6:13, 14). In the previous part of this defense he had shown his respect for Moses and his law. He now proceeds to show that he did not intend to speak with disrespect of the temple, or the holy places of their worship. He therefore expresses his belief in the Divine appointment of both the tabernacle (Acts 7:44–46) and of the temple (Acts 7:47).

According to the fashion. According to the pattern that was shown to him, by which it was to be made (Exodus 25:9, 40; Exodus 26:30). As God showed him a pattern, it proved that the tabernacle had his sanction. Against that Stephen did not intend to speak.
