The Israelites erected the tabernacle on the first day of the first month, almost exactly one year after the Israelites left Egypt (vv. 2, 17). This was about nine months after Israel had arrived at Mt. Sinai (cf. 19:1).
First, the text narrates God's command to erect the tabernacle (vv. 1-15). Moses' obedience to this command follows (vv. 16-33). Seven times in this chapter we read that Moses did exactly as the Lord commanded him (vv. 19, 21, 23, 25, 26, 29, 32; cf. Heb. 3:5).
"The writer's careful attention to the chronology of the events is important, for it shows that the restriction of the offering of the Passover lamb to the central worship center (Dt 16:1-8) could thus have already been carried out during this first celebration of the Passover in the wilderness."547
When the tabernacle stood complete, God descended in the cloud that so filled the tabernacle that neither Moses nor anyone else could enter it (vv. 34-39). The Jews called this cloud that indicated the special presence of God the shekinah (lit. residence, i.e., of God). This term does not appear in the Old Testament. It occurs in the Targums.548
Finally God was dwelling among His people. His redemption of them was now complete. He had liberated them from bondage in Egypt (chs. 1-15) and adopted them as His special treasure (chs. 15-40). He had made a covenant with them and now blessed them with His presence. He would guide them from then on "throughout all their journeys"(vv. 36, 38). The descent of God to take up residence in the midst of His people is therefore a fitting climax with which this book closes.
Moses, however, was not able to enter the tabernacle because of the cloud (v. 34). This indicates that more provisions were necessary before fellowship with God could continue. Leviticus explains those provisions.
