Greek Key Terms:
Context: On Day of Pentecost, after Holy Spirit's visible descent and disciples' speaking in tongues, Peter explains the phenomenon by quoting Joel 2:28-29. He declares "this is what was spoken by the prophet Joel" - identifying Pentecost as fulfillment of OT promise. The key expansion from Joel: "in the last days" (eschatological timeframe), and emphasis on universal Spirit outpouring across gender, age, and social status. "Your sons and daughters will prophesy" validates women's prophetic ministry in church age.

Connections:
Christological Connection: Christ is the Spirit-baptizer (Matthew 3:11; Acts 1:5). His ascension and exaltation led to Spirit's outpouring (Acts 2:33). The Spirit's work is to glorify Christ (John 16:14), so prophecy in church age testifies to Jesus (Revelation 19:10 - "testimony of Jesus is spirit of prophecy"). Miriam's isolated prophetic ministry finds fulfillment in Christ's gift of Spirit to all believers - making entire church a prophetic community bearing witness to Him. The pattern escalates: one prophetess (Miriam) → promise of many (Joel) → fulfillment for all (Pentecost) → ongoing reality (church age) → perfect worship (Revelation 15:3).
Connection Method(s): Promise-Fulfillment, Redemptive-Historical Progression — Joel's explicit promise of Spirit-outpouring on sons and daughters is declared fulfilled at Pentecost, escalating from one prophetess (Miriam) to the entire church as a prophetic community.
