Topical Lexicon
Overview

Strong’s Hebrew 3717 appears five times and consistently conveys the idea of making something “double” by folding it back upon itself. In every context the act of doubling serves a theological or symbolic purpose, whether strengthening sacred materials in the wilderness sanctuary or intensifying prophetic warning.

Tabernacle Coverings (Exodus 26:9)

The first occurrence is found in directions for the tabernacle curtains: “fold the sixth curtain double at the front of the tent”. The doubled edge produced a reinforced entrance, protecting what lay within from the elements and from impurity. By creating a thicker barrier at the point of access, the design highlighted the holy distinction between the camp of Israel and the dwelling place of God (Exodus 25:8). Practically, the extra layer reduced wear on a high-traffic area; theologically, it underscored that approach to the Holy One must be mediated and safeguarded.

Breastpiece of Judgment (Exodus 28:16; 39:9)

In priestly garments the same verb governs the construction of the breastpiece: “It must be square when folded over, a span long and a span wide” (Exodus 28:16; duplicated in Exodus 39:9). Folding produced a pouch in which the Urim and Thummim were placed (Exodus 28:30). The doubling therefore served two ends: (1) durability, to bear the weight of precious stones and continual handling, and (2) concealment, keeping the divinely appointed means of judgment close to the high priest’s heart yet hidden from casual sight. The object was both secure and symbolic, assuring Israel that Yahweh’s decisive word was kept safe and ever near the intercessor’s heart.

Prophetic Intensification (Ezekiel 21:14)

The final usage shifts from sanctuary craftsmanship to prophetic menace: “Let the sword strike twice, even three times” (Ezekiel 21:14). Here doubling amplifies the imminence and severity of judgment against rebellious Jerusalem. The repeated imagery—stroke after stroke—heightens urgency. Whereas in Exodus doubling protected holiness, in Ezekiel it signals relentless exposure to divine wrath when holiness is despised. The same concept, turned outward, becomes an unmistakable call to repentance.

Theological Motifs

1. Confirmation and Certainty: Elsewhere Scripture uses doubling to establish a matter (Genesis 41:32; Philippians 3:1). Each 3717 occurrence affirms certainty—whether of divine presence, priestly intercession, or coming judgment.
2. Protection and Preservation: The doubled curtain and breastpiece guarded what was sacred, anticipating the believer’s security “hidden with Christ in God” (Colossians 3:3).
3. Intensification of Judgment: Ezekiel’s doubled sword anticipates final reckoning, reminding readers that grace rejected becomes judgment intensified.

Christological Foreshadowing

The tabernacle foreshadows the incarnate Christ who “tabernacled among us” (John 1:14). The doubled curtain prefigures His perfectly sufficient mediation; the folded breastpiece anticipates His bearing the names of His people over His heart (Hebrews 4:14–16). In Ezekiel the doubled sword anticipates the “two-edged sword” proceeding from the risen Lord’s mouth (Revelation 1:16), assuring both salvation and judgment are consummated in Him.

Ministry Application

1. Craftsmanship for God’s glory: Every detail, even a simple fold, matters in service. Excellence in small things upholds the testimony of a holy God.
2. Intercession with integrity: Just as the high priest secured the Urim and Thummim within a doubled pouch, ministers today guard the Word and discernment entrusted to them.
3. Urgency in proclamation: Ezekiel’s doubled sword urges clear, repeated warnings. Faithful servants must not soften Scripture’s calls to repentance.

Summary

Strong’s 3717 unites themes of reinforcement, concealment, and intensification. From wilderness sanctuary to prophetic oracle, the doubled fold witnesses to God’s unwavering commitment to secure His people, reveal His will, and execute His judgments.
