Presume you mean "It was a constant struggle for the prophets to keep the Israelites from worshiping the Lord other gods."
Or alternatively
"It was a constant struggle for the prophets to keep the Israelites from worshiping only the Lord."
Same difference.
You are correct, the Israelites of the Old Testament were badly compromised when it came to taking after other gods. Some would say this arose partly from the split of the nation prior to entering Egypt. Others would say it arose from Joshua's failure to utterly destroy the inhabitants of the land during its conquest.
In fact, one may have led to another. The conquering Israelites, having been forged into a single religio-ethnic group by 400 years in Egypt and 40 more years in the Sinai, would have encountered the descendants of the Israelites who had remained behind in Canaan. However, the situation would have been complicated by generation upon generation of intermarriage between various tribes and peoples in the region. Sorting out who could be legitimately attacked and eliminated was very difficult if not impossible.
As for the program, I'll wait and see it before deciding whether or not it is anything more than just another left wing academic attempt to delegitimize Israel by attacking Judaism and Christianity.
Thank you, you are correct the second was my intended statement. Darn these old eyes!! They see what I intended to type, not what I did type <]:)
