The thing that gets me is that, that verse, translated from the Hebrew (see JPS Bible online) is nothing like what British Israelism claims it to be.
31 thus saith the L-rd GOD: The mitre shall be removed, and the crown taken off; this shall be no more the same: that which is low shall be exalted, and that which is high abased. 32 A ruin, a ruin, a ruin, will I make it; this also shall be no more, until he come whose right it is, and I will give it him.
I guess one would need know what the "it" is that was to be overturned three times. My guess would be that the "it" is that Stone of Scone, or some call Jacob's pillar that just recently was returned to Scotland.
I've read about it, stuff like E Raymond Capt's "Stone of Destiny" but I'm not sold. Interesting study though - Jacob's Pillar I mean, and the idea that the same rock upon which he rested his head was the same rock from which Moses obtained precious water for the Israelites. Not sure I buy that it is the same one that sat under the British/Scottish throne forever. It might be, but the "proof" seems spotty.
What is pointed to is the future as it is Christ that is to be the He that has the right to "it".
Meaning the throne of David? Agreed. The whole promise from Jeremiah 33, again from the JPS Bible -
14 Behold, the days come, saith HaShem, that I will perform that good word which I have spoken concerning the house of Israel and concerning the house of Judah. 15 In those days, and at that time, will I cause a shoot of righteousness to grow up unto David; and he shall execute justice and righteousness in the land. 16 In those days shall Judah be saved, and Jerusalem shall dwell safely; and this is the name whereby she shall be called, HaShem is our righteousness. 17 For thus saith HaShem: There shall not be cut off unto David a man to sit upon the throne of the house of Israel; 18 neither shall there be cut off unto the priests the Levites a man before Me to offer burnt-offerings, and to burn meal-offerings, and to do sacrifice continually.
I agree with the rest of your post, re Abraham, Esau and Jacob. Sending you freepmail.
