耶利米書 27:22 哈拉卡：Mishneh Torah, Kings and Wars

A person should always dwell in Eretz Yisroel, even in a city where most of the residents are not Jewish, rather than live outside of the Land in a city where most of the residents are Jewish. For anyone who leaves the Land is considered as if he worships idols, as it says, “for they have driven me out this day that I should not cleave to the inheritance of the Lord, saying, ‘go serve other gods’” (I Samuel 26:19). And regarding the calamities it says, “Neither shall they enter into the land of Israel” (Ezekiel 13:9). Just as it is forbidden to leave the Land, so it is forbidden to leave Babylon for any other country, as it says, “They shall be carried to Babylon, and there shall they be” (Jeremiah 27:22).
