Exodus 40:20: God's instructions?
How does Exodus 40:20 reflect God's instructions to Moses?

Text

“Moses took the tablets of the Testimony and placed them inside the ark. He attached the poles to the ark and put the mercy seat on top of the ark.” (Exodus 40:20)


Immediate Narrative Context

Exodus 40 records the final assembly of the tabernacle. Verse 16 summarizes, “Moses did everything just as the LORD had commanded him,” then verses 17–33 list eight specific actions that correspond point-for-point to earlier divine instructions. Verse 20 is the climactic obedience related to the ark, the first piece of furniture described in Exodus 25 and the theological heart of the sanctuary. Immediately after these acts, “the cloud covered the Tent of Meeting, and the glory of the LORD filled the tabernacle” (40:34), demonstrating that precise compliance with the instructions was prerequisite to God’s dwelling among His people.


Divine Instructions Concerning the Ark

1. Place the Testimony inside (Exodus 25:16).

2. Set the mercy seat (kapporet) on top (Exodus 25:21).

3. Insert the poles and leave them in place for transport (Exodus 25:14-15).

4. Handle only by the poles (Numbers 4:5-6, 15).

Exodus 40:20 matches each command verbatim, confirming that Moses neither added nor omitted a detail. The Septuagint, the Samaritan Pentateuch, and the Dead Sea Scroll fragment 4Q22 all attest to the same sequence, underscoring textual stability.


Covenantal Focus: Tablets Within the Ark

The “tablets of the Testimony” (Exodus 31:18; 34:28) are the covenant document. Housing them inside the ark signifies that God’s law is central, guarded by His presence above the mercy seat. Deuteronomy 10:1-5 recounts the same placement, and Hebrews 9:4 recalls it as enduring through Israel’s wilderness era, reinforcing the unbroken connection between covenant and presence.


The Mercy Seat: Propitiatory Symbolism

The solid-gold kapporet forms a lid where blood is sprinkled annually on the Day of Atonement (Leviticus 16:14-15). Its placement “above” the law anticipates substitutionary atonement: guilt covered, wrath satisfied, relationship restored. Romans 3:25 explicitly identifies Christ as the hilastērion (mercy seat), validating the typology.


Exactness of Obedience—A Theological Pattern

The phraseology “just as the LORD commanded Moses” occurs seven times in Exodus 40 (vv. 19, 21, 23, 25, 27, 29, 32). Ancient Near-Eastern treaty formulas likewise repeated obedience clauses to stress loyalty; Scripture adopts this literary device to underline Israel’s covenant fidelity at this decisive moment.


Liturgical and Behavioral Implications

• Reverence: Only consecrated priests may approach; poles prevent casual contact, prefiguring holiness boundaries (Numbers 4:19-20).

• Mobility with sanctity: The poles enable wilderness travel without desacralizing the ark—a model for carrying divine truth into daily life while guarding its sanctity.

• Centrality in worship: When camped, the ark rested at the tabernacle’s core; when marching, it led (Numbers 10:33), illustrating that divine revelation directs both worship and journey.


Typological Fulfillment in Christ

Tablets = divine standard, Ark = incarnate Word containing law, Mercy Seat = cross where blood is applied. John 1:14 echoes tabernacle imagery (“the Word became flesh and tabernacled among us”), and Revelation 11:19 locates the ark in the heavenly temple, signifying completion in the Lamb.


Archaeological Corroboration

While the original ark is lost, parallels exist:

• Gold-plated wooden chests with carrying poles in Tutankhamun’s tomb (14th century BC) exhibit analogous construction techniques.

• Sinai nomadic camp layouts discovered at Ein Qadis and Feiran demonstrate centrally sited sacred spaces, matching the tabernacle’s functional logic.

These findings validate the plausibility of the Exodus description within its Late Bronze Age context.


Practical Reflection

Exodus 40:20 models trust that God’s detailed directives are life-giving, not burdensome. Obedience positions the community to experience His manifest presence, a principle still operative: “If anyone loves Me, he will keep My word, and My Father will love him, and We will come to him and make Our home with him” (John 14:23).


Summary

Exodus 40:20 mirrors earlier divine commands with meticulous fidelity, places covenant law at the sanctuary’s heart, installs the mercy seat as a sign of forthcoming atonement, and sets a pattern for worship that the New Testament declares fulfilled in Christ. By doing precisely “as the LORD commanded,” Moses secures both historical alignment with the instructions of Exodus 25 and theological anticipation of redemptive reality.
