In Malachi 1 its stated that the covenant was broken, and that God cursed their blessings.
Malachi 1
2 If ye will not hear, and if ye will not lay it to heart, to give glory unto my name, saith the Lord of hosts, I will even send a curse upon you, and I will curse your blessings: yea, I have cursed them already, because ye do not lay it to heart.
Your hearts in the right place, but the Bible says that people come to hate God once they become reprobate. Romans 1 says that people who continually reject God are eventually rejected by God in turn, and that God "gives them up" to a reprobate mind, removing his spirit from them, and the lusts of their hearts turn to those things which are not convenient nor common to man (ex. sodomy).
The book of Isaiah describes a people who reject the Lord their God and who therefore are over run by strangers (foreigners) from the east.
ISAIAH
1:7 Your country is desolate, your cities are burned with fire: your land, strangers devour it in your presence, and it is desolate, as overthrown by strangers.
2:6 Therefore thou hast forsaken thy people the house of Jacob, because they be replenished from the east, and are soothsayers like the Philistines, and they please themselves in the children of strangers.
ROMANS 1
20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
22 Professing themselves to be wise, they became fools
The Jews gained Christian support starting when their (((publishing companies))) funded the creation of the "Scofield Study Bible," which was a KJV with a bunch of pro-Jewish commentary, at the turn of the 20th century. The Jews then went on the fund the dissemination of various false translations, gradually moving farther and farther away from the KJV. This is important as words were changed and even whole verse and passages were removed from (((modern))) versions. Then they co-opted seminary schools. So both the pastor and the Bible were corrupted. The only way to come to knowledge of God is through his word (what more could he do in his vineyard, that he has not done in it?) and if the word is corrupted than people will stray from the truth.
KJV is the only acceptable English version, I can't speak for other languages. You know a tree by its fruit; Great Britain and the USA did very well when they used the KJV exclusively.
There are many problems and Jews are one of them.
I went through that phase but there is no reason to ever stray from the doctrine plainly stated in the KJV. I ended up with a nasty case of demonic attachment, seriously bad, don't fuck around with extra-biblical mysticism.
Jews were already all over the Mediterranean from Judea to Egypt, Rome, and Spain in Biblical times.
