NRSV

[1] See, a day is coming for the LORD, when the plunder taken from you will be divided in your midst. [2] For I will gather all the nations against Jerusalem to battle, and the city shall be taken and the houses looted and the women raped; half the city shall go into exile, but the rest of the people shall not be cut off from the city. [3] Then the LORD will go forth and fight against those nations as when he fights on a day of battle. [4] On that day his feet shall stand on the Mount of Olives, which lies before Jerusalem on the east; and the Mount of Olives shall be split in two from east to west by a very wide valley; so that one half of the Mount shall withdraw northward, and the other half southward. [5] And you shall flee by the valley of the LORD’s mountain, for the valley between the mountains shall reach to Azal; and you shall flee as you fled from the earthquake in the days of King Uzziah of Judah.  Then the LORD my God will come, and all the holy ones with him.

[6] On that day there shall not be either cold or frost. [7] And there shall be continuous day (it is known to the LORD), not day and not night, for at evening time there shall be light.

[8] On that day living waters shall flow out from Jerusalem, half of them to the eastern sea and half of them to the western sea; it shall continue in summer as in winter. 

[9] And the LORD will become king over all the earth; on that day the LORD will be one and his name one. 

LXX

[1] See the days of the Lord are coming, and your spoils shall be divided in you. [2] And I shall gather all the nations together against Jerusalem unto war, and the city shall be conquered, and they shall plunder the houses, and the women they shall rape, and half of the city shall go out in captivity, but the remnant of my people shall not be utterly destroyed from the city. [3] And the Lord shall come and draw up in battle array against these nations just as a day of his marshaling in a day of war. [4] And his feet shall stand on this day upon the Mount of Olives which is opposite Jerusalem in the east; and the Mount of Olives shall split in two, half of it to the east and half of it to the sea, an exceedingly great chasm; and half of the mountain shall slope to the north and half of it to the south. [5] And the chasm of my mountain shall be stopped up, and the chasm of the mountain shall be joined together unto Iasol and shall be stopped up just as it was stopped up in the days of the earthquake in the days of Uzziah King of Judah; and the Lord my God will come and all the Holy Ones with him. 

[6] And on this day there shall not be light and cold and frost. [7] It shall be one day , and this day is known to the Lord, and not day and not night, and before evening it shall be light. 

[8] And in these days the living water shall come from Jerusalem, half of it into the first sea and half of it into the last sea, and in summer and spring it shall be thus. [9] And the lord shall be unto a kingdom upon all the earth; on this day the Lord shall be one and his name shall be one. 

Notes on Text

Here we see the text turn straightforwardly to promises of destruction, which had been indicated more obliquely in the previous chapter. Some of the language here is highly symbolic, with the Mount of Olives being described as splitting and aligned to the four cardinal directions.  The reference to King Uzziah here is quite interesting.  His reign is described in 2 Chronicles 26 and 2 Kings 15:1-7 (Here he is listed as Azariah), and he is also mentioned in Amos 1:1 (as well as the earthquake during his reign). The description of his reign in 2 Kings is quite succinct, he is described as having done what is right in the eyes of the Lord but nevertheless permitting sacrifices to continue in the high places (this is a common gripe in 1 & 2 Kings), and being struck with leprosy.  This story is elaborated on in 2 Chronicles, which says that after a period a time in which he was faithful, he grew proud an tried to offer incense in the temple (which was only allowed for the Aaronic priesthood), and so God struck him with leprosy as punishment.  In Amos, the prophecy is dated to the reign of Uzziah, two years before the earthquake.  Just very briefly skimming Amos, it is mostly promising destruction upon many peoples for various acts of violence, injustice, and impiety, and presumably the earthquake is mentioned to strengthen the message of the prophecy.  “See, God is promising these punishments and also do you remember this earthquake that was obviously one of them?!” 

In the NRSV, all of this language about earthquakes is used to describe the creation of a passage through which a remnant of the population is able to flee Jerusalem.  In the LXX, this passage is stopped up and the remnant remains in Jerusalem (although is presumably also kept safe).  This is all quite reminiscent of the previous passage.  Although the remnant is a different portion (a third in 13:8, a half here), in both cases there is a remnant, and in both cases it seems that the remnant must suffer prior to salvation (note that the pillaging and raping is described as having occurred prior to any salvation).  This variation, however, is much more closely tied to the experience of the Babylonian exile and the destruction of half the people of Jerusalem is the result of their captivity and exile.
