Luke's catalogue of nations at Pentecost (Acts 2:9-11 — Parthians, Medes, Elamites, Mesopotamia, Judea, Cappadocia, Pontus, Asia, Phrygia, Pamphylia, Egypt, Libya, Rome, Cretans, Arabs) is a designed reactivation of the Table of Nations (Genesis 10), the ethno-linguistic map for which Babel (Genesis 11:1-9) supplies the explanation. The allusion is structural and, in the Greek, verbal, and its inversions are deliberate. The verbal hinge sits just before the list, at Acts 2:6: the crowd "came together in bewilderment" — συνεχύθη, the very verb the Septuagint uses for the LORD's confusing of the language at Babel (συγχέω, LXX Genesis 11:7, 9) — "because each one heard them speaking his own language," sharing with LXX Genesis 11:7 not only the verb but its frame of each one hearing. The tongues (γλῶσσαι) that rest on the disciples and fill the crowd's ears (Acts 2:3-4, 11) are the γλῶσσα the LXX says was confused at Babel (Genesis 11:7). At Babel God "came down" to confuse the one language and scatter the builders ("Come, let Us go down and confuse their language," Gen 11:7); at Pentecost the Spirit comes down and the gathered "God-fearing Jews from every nation under heaven" (Acts 2:5) each hear "the wonders of God" in their own tongues (2:11) — the multiplied languages no longer divide but each become a vehicle of one gospel. Babel's builders sought "a name for ourselves" (Gen 11:4) and were scattered; at Pentecost "everyone who calls on the name of the Lord will be saved" (2:21) and the scattered are gathered into one body. The confusion of tongues imposed in judgment is not erased but redeemed: diversity of language remains, while its dividing power is broken. Luke thus stages the inauguration of the canon-wide scattered-to-gathered reversal that the prophets promised (Zephaniah 3:9; Isaiah 66:18) and Revelation 7:9 consummates.
