One writer identified three major problems the interpreter faces as he or she seeks to understand God's revelation concerning the tabernacle.438
1. What was the length of the cubit, the standard measure of length? This is a problem because various nations had different lengths for their cubits. A cubit was the distance between the elbow and the middle fingertip. The length ranged from about 17 inches to 21 inches, but there is good reason to believe the Hebrew cubit at this time was 17.5 inches or about one and a half feet.
2. What about the information omitted in the text? Anyone who has tried to make a model or detailed drawing of the tabernacle and its furnishings has experienced frustration. The data given in the text is incomplete. Undoubtedly God revealed all the details to Moses. However, He has preserved only those details necessary for our understanding of the fundamental significance and functioning of the tabernacle in Scripture.
3. What was the exact shape of the tabernacle? The text does not enable us to know for certain if it had a flat roof or a gabled roof formed by a ridge pole. Both possibilities have problems connected with them, but the flat roof design seems more probable all things considered. A gabled roof would increase the measurement of the roof beyond the width of 15 feet so the curtains over the roof and sides would not fully cover the sides.
Another problem is the extent of typological teaching that God intended. A "type"is a divinely intended illustration. Thus all types are illustrations, but not all illustrations are types. How much detail did God intend to illustrate His character and relationship with His people?
We know the major aspects of the tabernacle and its furnishings are types because the New Testament writers identified them as such (Heb. 5:4-5; 8:5; 9:23-24; 9:8-9; 10:20). However the amount of detail Moses preserved and the obvious correspondence of certain details not identified as types have led many commentators to conclude that God intended these details to be instructive too. Some commentators have taken this teaching to extend to the numbers and colors used that, in some cases in scriptural usage, do have symbolic significance. Some commentators have taken this too far in the judgment of other students of Exodus.
I prefer a cautious approach myself. It seems to me that there are many illustrations of New Testament truth in the Old Testament. This seems clear in view of the amount of detail God preserved here. It also seems clear since the illustrative significance of some features of the tabernacle is so obvious even though the New Testament does not identify them as types. An extremely conservative approach would be to identify as types only those things that the New Testament calls types (Gr. typos, cf. antitypos). These would include Adam (Rom. 5:14), the wilderness wanderings of Israel (1 Cor. 10:6, 11), the holy place in the tabernacle and temple (Heb. 9:24), and the flood in Noah's day (1 Pet. 3:21). We could refer to other foreshadowings simply as illustrations.439
Josephus, following Philo, interpreted the tabernacle, its furniture, and the priests' garments allegorically. He wrote that the seven branches of the lampstand represent the courses of the planets. The colors of the curtains and clothing represent the four elements (earth, water, air, and fire). The two shoulder stones stand for the sun and moon. The 12 breastplate stones represent the 12 months or the 12 signs of the Greek zodiac.440His suggestions do not seem to be the best interpretations of the significance of these things.
Note that the order in which Moses described the things associated with the tabernacle in the text is not what one would normally expect. For example, we would expect that after the description of the altar of burnt offerings we would have a description of the laver. The altar of burnt offerings was the major piece of furniture in the courtyard and the first one the Israelite would meet as he entered the courtyard. The laver was the second most prominent item. It would catch the Israelite's eye next. It was also the object between the altar and the tabernacle. However instead we read about the altar of burnt offerings, then the priestly vestments, then the consecration of Aaron, and then the laver. This order is due to the two emphases in the revelation. First, Moses described things that primarily manifest God, and second, things dealing with His people's fellowship with God. The author described first things in the holy of holies where God dwelt, then things in the holy place, then things in the courtyard. This order focuses attention on the presence of Yahweh among His people, which was the most important feature of Israel's life. The tabernacle itself also reflects the importance of Yahweh's presence at the center of His people.
"The tabernacle was built on a ratio of 2:1 and on a radiating decrease value of metal: gold, silver, bronze, from the center [where God dwelt] to the outer edges."441
The materials that the Israelites were to use in the construction of the tabernacle and its worship were the finest and rarest available. This reflected the fact that nothing but the best was appropriate for response to Yahweh. What was at the center of priestly concern was not a building or a ritual but the Lord Himself, present as a gift to His people.442
