Zechariah 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 

Zechariah 14:17

14:17 But if any of the nations anywhere on earth refuse to go up to Jerusalem ²  to worship the King, the Lord who rules over all, they will get no rain.

[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.”

[14:17]  ² sn The reference to any…who refuse to go up to Jerusalem makes clear the fact that the nations are by no means “converted” to the Lord but are under his compulsory domination.
