עַד־בֹּאִי֩ וְלָקַחְתִּ֨י אֶתְכֶ֜ם אֶל־אֶ֣רֶץ כְּאַרְצְכֶ֗ם אֶרֶץ֩ דָּגָ֨ן וְתִיר֜וֹשׁ אֶ֧רֶץ לֶ֣חֶם וּכְרָמִ֗ים אֶ֣רֶץ זֵ֤ית יִצְהָר֙ וּדְבַ֔שׁ וִֽחְי֖וּ וְלֹ֣א תָמֻ֑תוּ וְאַֽל־תִּשְׁמְעוּ֙ אֶל־חִזְקִיָּ֔הוּ כִּֽי־יַסִּ֤ית אֶתְכֶם֙ לֵאמֹ֔ר יְהוָ֖ה יַצִּילֵֽנוּ׃
until I come and take you away to a land like your own land, a land of corn and wine, a land of bread and vineyards, a land of olive-trees and of honey, that ye may live, and not die; and hearken not unto Hezekiah, when he persuadeth you, saying: The LORD will deliver us.
Rashbam
העביר אותו לערים, a stratagem also employed by Sancheriv when he conquered the northern Kingdom of Israel and forcibly exchanged the populations of that kingdom with people from the north. (compare Kings II 18,32). The purpose behind this was to prevent uprisings by populations who had no roots in their countries and therefore had no good reason to start a rebellion.
