What Does Exodus 25:4 Mean?

"They shall make an ark of acacia wood. Two cubits and a half shall be its length, a cubit and a half its breadth, and a cubit and a half its height. You shall overlay it with pure gold, inside and outside shall you overlay it, and you shall make on it a molding of gold around it." The ark of the covenant (aron ha'berit) is the tabernacle's most holy object, the innermost piece of furniture, placed behind the veil in the holy of holies.

Three dimensions (2.5 x 1.5 x 1.5 cubits, approximately 45" x 27" x 27") define a chest large enough to contain the tablets of the covenant plus the Torah scroll (Deuteronomy 31:26) and the jar of manna (Exodus 16:33) and Aaron's staff (Numbers 17:10). The ark is the covenant's physical container.

Gold-inside-and-outside overlay of an acacia wood core is the ark's construction principle: and of the incense altar and the table as well: the wood provides structural integrity while the gold provides the purity-holiness exterior appropriate for the most holy furniture. The gold-overlay principle is the tabernacle's material theology: the pure gold that covers these holy objects is the material expression of the divine purity that the tabernacle aims to represent and approximate. No raw wood, with its impurity, its natural state, its unconsecrated material nature, is visible on the tabernacle's innermost furniture. All is gold.

The ark's theological function is defined by 1 Kings 8:9 ("there was nothing in the ark except the two tablets of stone that Moses put there at Horeb") and Hebrews 9:4 (also containing "the golden urn holding the manna, and Aaron's staff that budded, and the tablets of the covenant").

The ark holds the covenant's founding documents (the stone tablets) and its two greatest provision-miracles (the manna jar, Aaron's budding-staff). The covenant container holds the covenant-text alongside the covenant's miraculous provisions: the law and the grace together. The ark that Israel carried through the wilderness, that crossed the Jordan, that sat in the holy of holies for centuries, is the covenant's most concrete physical symbol.
