CHAPTER 4 Dec. 6 
The Mountain of Yahweh’s Temple 
But in the latter days, it will happen that the mountain of Yahweh’s temple will be established on the top of the mountains, and it will be exalted above the hills; and nations will stream to it. 2Many nations will go and say, Come, and let us go up to the mountain of Yahweh, and to the house of the God of Jacob; and He will teach us of His ways, and we will walk in His paths. For out of Zion will go forth the law, and the word of Yahweh from Jerusalem; 3and He will judge between many peoples, and will decide concerning strong nations afar off. They will beat their swords into plowshares, and their spears into pruning hooks. Nation will not lift up sword against nation, neither will they learn war any more. 4But they will sit every man under his vine and under his fig tree; and no one will make them afraid: for the mouth of Yahweh of Armies has spoken. 5Indeed all the nations may walk in the name of their gods; but we will walk in the name of Yahweh our God for ever and ever. 6In that day, says Yahweh, I will assemble that which is lame, and I will gather that which is driven away, and that which I have afflicted; 7and I will make that which was lame a remnant, and that which was cast far off a strong nation: and Yahweh will reign over them on Mount Zion from then on, even forever. 8You, tower of the flock, the hill of the daughter of Zion, to you it will come, yes, the former kingdom will return, the kingdom will come to the daughter of Jerusalem. 9Now why do you cry out aloud? Is there no king in you? Has your counsellor perished, that pains have taken hold of you as of a woman in travail? 10Be in pain, and labour to bring forth, daughter of Zion, like a woman in travail; for now you will go forth out of the city, and will dwell in the field, and will come even to Babylon. There you will be delivered. There Yahweh will redeem you from the hand of your enemies. 11Now many nations have assembled against you, that say, Let her be raped, and let our eye gloat over Zion. 12But they don’t know the thoughts of Yahweh, neither do they understand His counsel; for He has assembled them like the sheaves to the threshing floor. 13Arise and thresh, daughter of Zion; for I will make your horn iron, and I will make your hoofs brass; and you will beat in pieces many peoples: and I will devote their gain to Yahweh, and their substance to the Lord of the whole earth.

Commentary

4:1-4 A clear prophecy of the literal establishment of the Kingdom of God on earth, based around Jerusalem. ‘Mountains’ are symbolic of kingdoms.
4:4 Vine… fig tree- These words were quoted by Rabshakeh, in offering the Jews this very situation in pagan Assyria (2 Kings 18:31,32). The world around us in its advertisements and glossy images is in fact a fake Kingdom of God, imitating the true Kingdom of God. And so the choice is highlighted for us- between the kingdoms of this world for today, and the eternal Kingdom of God tomorrow.
For the mouth- The wonder of the process of inspiration is that the black print we read on white paper in the Bible is the very mouth of God speaking to us.
4:8 The Kingdom of God which Jesus will establish at His return will in fact be a re-establishment of the Kingdom which was earlier, when Yahweh was Israel’s Kingdom on earth (Ez. 21:25-27; 1 Chron. 29:23). This “former Kingdom” will be restored, again on earth, but to a far more glorious extent.
4:10 How was the travailing daughter of Zion to be delivered / rescued in Babylon after having been taken captive there from Jerusalem by the Babylonians? Surely in that there, God intended a spiritual revival of the people, there they would hear Ezekiel’s appeal to repent, which if responded  to would enable them to build the temple which he had described (Ez. 43:10,11) and thus usher in a Messianic Kingdom.  God had so many wonderful plans for His people which they didn’t allow to come true for them.
4:12 God assembles the nations to judge / thresh them, but they assemble themselves (:11).This is part of a large Biblical theme- that those who are judged in fact judge themselves. The only ones who will be rejected by God are those who themselves don’t wish to be in His Kingdom.
