Quotation zu Wajikra 25:38

"Our Rabbis were taught: Always shall a man prefer to live in the land of Israel, even in a town where the majority is nonJews, than outside of the land of Israel, even though its majority consists of Israelites; for whoever lives in the land of Israel is like one who has a God, while one who lives outside of the land of Israel is like one who has no God, as it is said (Lev. 25, 28) To give unto you the land of Cannan to be unto you a God. Is it then really considered that whoever lives outside of the land of Israel has not a God? We must say that this means to tell us that whoever lives outside of the land of Israel is considered as if he would serve idols. We also find it so with David (I Sam. 26, 19) Because they have driven me out this day so that I cannot attach myself on the inheritance of the Lord, saying, 'Go, serve other Gods.' Who is then the man who would say to David: "Go and serve idols." We must therefore say that whoever lives outside of the land of Israel is considered as if he would serve idols.
