וְהָיְתָ֣ה יָדִ֗י אֶֽל־הַנְּבִיאִ֞ים הַחֹזִ֣ים שָׁוְא֮ וְהַקֹּסְמִ֣ים כָּזָב֒ בְּס֧וֹד עַמִּ֣י לֹֽא־יִהְי֗וּ וּבִכְתָ֤ב בֵּֽית־יִשְׂרָאֵל֙ לֹ֣א יִכָּתֵ֔בוּ וְאֶל־אַדְמַ֥ת יִשְׂרָאֵ֖ל לֹ֣א יָבֹ֑אוּ וִידַעְתֶּ֕ם כִּ֥י אֲנִ֖י אֲדֹנָ֥י יְהוִֽה׃
我的手必攻擊那些看見虛假異象、占卜謊言的先知。他們必不得列在我子民的會中，不得記錄在以色列家的冊籍上，也不得進入以色列的土地；你們就知道我是主永恆者。
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).
