Zechariah 12:10
8 On that day the Lord himself will defend the inhabitants of Jerusalem, so that the weakest among them will be like mighty David, and the dynasty of David will be like God, like the angel of the Lord before them. 9 So on that day I will set out to destroy all the nations that come against Jerusalem. 10 “I will pour out on the kingship of David and the population of Jerusalem a spirit of grace and supplication so that they will look to me, the one they have pierced. They will lament for him as one laments for an only son, and there will be a bitter cry for him like the bitter cry for a firstborn. 11 On that day the lamentation in Jerusalem will be as great as the lamentation at Hadad Rimmon in the plain of Megiddo. 12 The land will mourn, each clan by itself—the clan of the royal household of David by itself and their wives by themselves; the clan of the family of Nathan by itself and their wives by themselves;
Matthew 24:30
28 Wherever the corpse is, there the vultures will gather. 29 “Immediately after the suffering of those days, the sun will be darkened, and the moon will not give its light; the stars will fall from heaven, and the powers of heaven will be shaken. 30 Then the sign of the Son of Man will appear in heaven, and all the tribes of the earth will mourn. They will see the Son of Man arriving on the clouds of heaven with power and great glory. 31 And he will send his angels with a loud trumpet blast, and they will gather his elect from the four winds, from one end of heaven to the other. 32 “Learn this parable from the fig tree: Whenever its branch becomes tender and puts out its leaves, you know that summer is near.
Notes and References
"... We have seen how prominent the theme of the conversion of the nations is in Revelation, emerging first in chapter 11 and reaching its culmination in the New Jerusalem. But the theme also appears in a particular way in both the prologue (1:1-8) and the epilogue (22:6-21) to the book. In both cases John cites Old Testament prophecies from the testimonia tradition which would already have been familiar to his readers. The purpose is to indicate that the conversion of the nations is already part of the church's hope founded on the scriptures. Whereas the revelation of the way this hope is to be realized is novel — the content of the hitherto sealed scroll — the hope itself is not novel. The traditional testimoniumin the prologue is 1:7. Comparison with Matthew 24:30 shows this to be traditional ... These two passages'" both conflate Daniel 7:13 and Zechariah 12:10,12, although they do so in different orders, and although Revelation quotes more of Zechariah than Matthew does, while Matthew quotes more of Daniel than Revelation does. Comparison with Zechariah 12:10, 12 LXX, will enable us to see that the agreement between Revelation and Matthew is not coincidental ..."
