The two tribes that are the "Lost Tribes" are Ephraim & Dan. Both did many things against the Lord, but did not look unto the Lord to be saved basically.

Will,

Do you have references/quotes for that?

The book is called "The Cross and it's shadow" by Stephen Haskell, the chapter is called Lost Tribes, but apparently it is not mentioned in the online book and even that chapter is not available. What I can do is type up the highlights of each of the tribes problem. I will have to summarize it somehow, but that is an option.

I have that book, therefore, I will look up that chapter and read it for myself.

If I see anything real interesting, I will, either quote it, or post about it here.

You can also look at Revelation 7 where Ephraim & Dan are not mentioned.
There was idolatry, and I believe Jereboam caused the people of Israel to sin by making golden calf's and he said that they had delivered them from Egypt etc etc.

However it is important to note that the other tribes were not always righteous, such as the tribe of Asher, but eventually the people of these tribes looked unto the Lord even though they had all these faults whereas Ephraim & Dan did not.

I can attempt to scan the pages from the Lost Tribes and make it available, but I have to make sure its a good quality, and its a few pages, and never having done that I am not sure how big the files would be.I'll see what I can figure out.

Here's an idea. The verses for the tribes falling, BUT I did find an error in the chapter.
You see the author said that When the tabernacle was built in the wilderness, God especially endowed Aholiab of he tribe of Dan with wisdom to devise cunning works of gold etc etc. This is not correct because it was Bezaleel the son of Uri, the son of Hur of the tribe of Judah.
This is on page 374, and the verses used for it is Ex.31:3-6, so keep that part in mind.

It is actually the very last chapter.

Interesting reading, however, it will take some time to post some of the relevant information here that would relate to the intent of this topic, but, if my intent doesn't fail me, I hope to eventually post it here, unless Will beats me to it, which I hope he will.

Will,

I just noticed your other posts here.

If you can "scan the pages from the Lost Tribes and make it available", that will be great!

I'll make a test scan and see how it looks.
God Bless,

When one of you gets the time to scan, I am very interested in seeing what the book has to say. When was the book first published?
