Zakharia 8:20-22

8:20 The Lord who rules over all says, ‘It will someday come to pass that people – residents of many cities – will come. 8:21 The inhabitants of one will go to another and say, “Let’s go up at once to ask the favor of the Lord, to seek the Lord who rules over all. Indeed, I’ll go with you.”’ 8:22 Many peoples and powerful nations will come to Jerusalem to seek the Lord who rules over all and to ask his favor.

Zakharia 13:9

13:9 Then I will bring the remaining third into the fire;

I will refine them like silver is refined

and will test them like gold is tested.

They will call on my name and I will answer;

I will say, ‘These are my people,’

and they will say, ‘The Lord is my God.’” ¹ 

Zakharia 14:16

14:16 Then all who survive from all the nations that came to attack Jerusalem will go up annually to worship the King, the Lord who rules over all, and to observe the Feast of Tabernacles. ² 

[13:9]  ¹ sn The expression I will say ‘It is my people,’ and they will say ‘the Lord is my God’ is reminiscent of the restoration of Israel predicted by Hosea, who said that those who had been rejected as God’s people would be reclaimed and once more become his sons and daughters (Hos 2:23).

[14:16]  ² sn Having imposed his sovereignty over the earth following the Battle of Armageddon, the Lord will receive homage and tribute from all who survive from all the nations. The Feast of Tabernacles was especially associated with covenant institution and renewal so it will be appropriate for all people to acknowledge that they are vassals to the Lord at that time (cf. Deut 31:9-13; Neh 8:12-18; 9:1-38).
