Isaiah 60:15

Whereas thou hast been forsaken - Hebrew, ‘Instead of (תחת tachath) thy being forsaken,’ that is, thy subsequent prosperity shall come in the place of thy being formerly forsaken. The forsaking here refers to the various calamities, persecutions, and trials, which she had been called to endure.

So that no man went through thee - When the country was desolate and abandoned, so that no caravan passed from one part of it to another, or made it a thoroughfare in going to other lands (compare Lamentations 1:4; see the notes at Isaiah 34:10).

I will make thee an eternal excellency - Lowth, ‘An everlasting boast.’ Noyes, ‘Glory.’ I will make you forever honored or exalted, so that you shall no more be desolate and abased.

A joy of many generations - A subject of joy from generation to generation; that is, one age after another.
