Zechariah 14:4
14:4 On that day his feet will stand on the Mount of Olives which lies to the east of Jerusalem, and the Mount of Olives will be split in half from east to west, leaving a great valley. Half the mountain will move northward and the other half southward. 1
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. 2
1 sn This seismic activity provides a means of escape from Jerusalem so that the Messiah (the Lord), whose feet will stand on the Mount of Olives, may destroy the wicked nations in the Kidron Valley (the v. of Jehoshaphat, or of “judgment of the Lord”) without harming the inhabitants of the city.
2 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.”
