וַאֲבַדְתֶּ֖ם בַּגּוֹיִ֑ם וְאָכְלָ֣ה אֶתְכֶ֔ם אֶ֖רֶץ אֹיְבֵיכֶֽם׃
און איר װעט אונטערגײן צװישן די פֿעלקער, און דאָס לאַנד פֿון אײַערע פײַנט װעט אײַך אױפֿעסן.
Rashi
ואבדתם בגוים AND YE SHALL BE LOST AMONG THE NATIONS — when you are scattered about among the nations you will lose sight of each other (lit., “you will be lost from one another”) (cf. Rashi on v. 33; see also Sifra, Bechukotai, Chapter 8 1).
Tur HaArokh
ואכלה אתכם ארץ אויביכם, ”the land of your enemies will devour you.” This is characteristic of all people who are exiled to a strange country. The change of climate and water by themselves result in their being decimated in numbers.
Siftei Chakhamim
When you will be scattered you will be lost. But not really lost, because it is written (v. 44), “All this notwithstanding ... to annihilate them.”
