"THEE BALANCES TO WEIGH, AND DIVIDE THE HAIR" : One opinion says this is figurative and that they did not have such sensitive scales in those days. I however would hesitate to underestimate the technological capability of the Ancient Israelites at some stages. This aspect of weighing was seen (Breuer) to emphasize the Divine Providence in the events predicted as against mere caprice.

Ezekiel is referring to the fate of Jerusalem on the simple level. One third destroyed within the city, another third in the area around about, and the last third scattered and exiled. A similar use of dividing into threes concerning a coming calamity was found in Zechariah. Compare the verses and our commentary there:
<< AND IT SHALL COME TO PASS, THAT IN ALL THE LAND, SAITH THE LORD, TWO PARTS THEREIN SHALL BE CUT OFF AND DIE; BUT THE THIRD SHALL BE LEFT THEREIN. << AND I WILL BRING THE THIRD PART THROUGH THE FIRE, AND WILL REFINE THEM AS SILVER IS REFINED, AND WILL TRY THEM AS GOLD IS TRIED: THEY SHALL CALL ON MY NAME, AND I WILL HEAR THEM: I WILL SAY, IT IS MY PEOPLE: AND THEY SHALL SAY, THE LORD IS MY GOD>> [Zechariah 13:8-9].
The general explanation suggested is that some calamity will occur. Two-thirds of the world's people (including, by implication, two-thirds of the Israelites?) will perish. Part of the remaining third of non-Israelites and Israelites by descent will then accept the faith of Israel and identify as Israelites BUT then will come the troubles of Gog and Magog. There will be persecutions and the threat of extinction. Most of the non-Israelites who accepted the Israelite faith will back out and it will be mainly those of Israelite descent who remain attached to Israelite religion.

Here the indication is that the prophecy concerns all the House of Israel (i.e. including the Ten Tribes) but the specifics seem to indicate primarily Jerusalem of Judah.

"I will not cease from mental fight,Nor shall my sword sleep in my hand Till we have built JerusalemIn England's green and pleasant land" William Blake (1757-1827)

Is "JERUSALEM" always the literal Jerusalem in Scripture? It can also represent Judah in general. But can "JERUSALEM" in some contexts be also applicable to the Lost Ten Tribes? Just when I was considering this question I received in the mail a booklet from British Israel in the UK. It contains a review by Michael A. Clark of a book titled "New Jerusalem" by Adrian Gilbert. "New Jerusalem" means London. In 1666 there was the Great Fire of London after which part of the city had to be rebuilt. According to Mr. Clark (reviewing "New Jerusalem" by Adrian Gilbert):"Sir Christopher Wren, who was a leading figure in the newly formed Royal Society, led the group charged with this task [of designing the rebuilding of London] by Charles II. The direction that the rebuilding of this new city took was entirely shaped by the mystical and scientific
beliefs of this group. They believed that Britain had a predestined role as the new Israel, and London was waiting to take up its position as the prophesied New Jerusalem."

We have not kept the Law nor the will of the Almighty as we should have done.

We have not kept the judgments of God, nor even have we done as well on a moral level as the non-Israelite nations around us.

Again retribution is predicted against us and we divided into three part only one of which is to survive?

These predictions were fulfilled in the disasters that overcame the inhabitants of Jerusalem. The question is what does the future hold? OK everyone here (on this list) is a believer and probably lives a fairly righteous existence. How can we better ourselves? How much obligation do we have towards others? How can we help them? How can we help ourselves? Where does the solution lie?
