Source-critical scholarship attributes the detailed Tabernacle instructions of Terumah, along with the parallel construction account in Vayakhel-Pekudei, to the Priestly source with a high degree of consensus, based on their distinctive vocabulary and their close attention to precise measurement and material. What remains genuinely disputed among biblical historians is whether the elaborate portable sanctuary these chapters describe reflects an actual structure used during a wilderness period, whether it is a modest tent later elaborated in memory, or whether its full design was substantially shaped by, or modelled on, the later Jerusalem Temple and projected back onto the wilderness narrative; archaeology has not settled the question, since a tent shrine of this kind would leave little identifiable trace.
Traditional Jewish commentary is not engaged by this historical question and instead reads the Tabernacle's design as a revealed pattern shown to Moses on the mountain (Exodus 25:9), later commentators including Nachmanides treating the wilderness Tabernacle and the Jerusalem Temple as expressions of a single continuing sanctity rather than as separate structures needing historical reconciliation.
