Charles Ellicott Commentary Deuteronomy 28:65

"And among these nations shalt thou find no ease, and there shall be no rest for the sole of thy foot: but Jehovah will give thee there a trembling heart, and failing of eyes, and pining of soul;" — Deuteronomy 28:65 (ASV)

And among these nations you shall find no ease. — The repeated persecutions of the Jews by other nations in the time of their dispersion are among the most fearful and wonderful phenomena of history.

And failing of eyes. — “Looking for salvation, and it does not come” (Rashi). How many years have they gone on praying that they may keep the feast “next year” in Jerusalem? and still the hope is deferred.
