Zakharia 14:9

14:9 The Lord will then be king over all the earth. In that day the Lord will be seen as one with a single name. 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 

[14:9]  ¹ sn The expression the Lord will be seen as one with a single name is an unmistakable reference to the so-called Shema, the crystallized statement of faith in the Lord as the covenant God of Israel (cf. Deut 6:4-5). Zechariah, however, universalizes the extent of the Lord’s dominion – he will be “king over all the earth.”

[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).
