Isaiah
Isaiah 60:20BSB·traditional attribution

Your sun will no longer set, and your moon will not wane; for the LORD will be your everlasting light, and the days of your sorrow will cease.

Matthew Henry Presbyterian @wholebiblehenry

The happy and glorious state of the church is here further foretold, referring principally and ultimately to the Christian church and the spiritual peace of that, but under the type of that little gleam of outward peace which the Jews sometimes enjoyed after their return out of captivity. This is here spoken of, I. As compared with what it had been.

John Gill Reformed Baptist @doctorgill

Thy sun shall no more go down,.... This is a different sun from the former; this is the church's sun, and no other than the sun of righteousness, Christ Jesus; who has his risings and settings now, at least, in the apprehensions of his people; he sometimes withdraws himself, and is gone; and then returns again: but so it will not be in this state...

There shall be no national and spiritual obscuration again as formerly (Joe 2:10; Amo 8:9). mourning . . . ended-- (Isa 25:8; Rev 21:4).
