God’s stated purpose for the The tabernacle, a word meaning "tent," was a portable worship place for the Hebrew people after they left Egypt. It was said to contain the ark of the covenant. The plans for the tabernacle are dictated by God in Exodus 26. More, priesthood, and sacrificial system was to be continually present among Israel as the one who brought them out of Egypt and thus was their God.
A hasty scan through the extensive instructions for building the tabernacle might result in missing these verses. They articulate the importance of the instructions. It is serious business to have God dwell in the midst of the community. There is concern that God’s presence not be episodic. In one sense, it is clear that there is not a literal “exodus from Egypt” every day. But it would also not be desirable to have God merely pop in every once in a while. The tabernacle was to meet the need for everyday continuity (“throughout your generations” [29:42]). The presence of God does not merely trickle down from the priesthood. Moses' brother and spokesman, and Israel's first high priest. More and his sons are, indeed, consecrated but here God also meets with the Israelites as well as the priests. God’s dwelling among the Israelites is stressed through repetition in verses 45 and 46. The pronoun relationship of the A covenant is a promise or agreement. In the Bible the promises made between God and God's people are known as covenants; they state or imply a relationship of commitment and obedience. More is expressed: “I will be their God.” And at the core is the event that grounds the covenant, namely, the exodus from Egypt. All of the specificity around the tabernacle is not to derive something from God. Rather, it grows out of God’s desire to dwell among the Israelites.
