Some of the cooler links to the New Testament which I've been finding in the Minor Prophets:
1. The 4 horsemen didn't originate in Revelation 6:1-8, but in Zechariah 6:2-3.
2. The NT teaches (by allusion to the OT) that the Church, the gathering of God's people, is God's new temple. See Zech 4:7-9, then Eph 2:20 and 1 Peter 2:4-7.
3. Zephaniah 3:9 was Pentecost, like a 2x4 between the eyes: "For then I will restore to the peoples a pure language, that they all may call on the name of the LORD, to serve Him with one accord." 3 references to Acts 2, beginning, middle and end: language in vs 4, call on Yahweh vs 21, serving with one accord vs 46.
