King James Version (KJV)
Thy sun shall no more go down; neither shall thy moon withdraw itself: for the LORD shall be thine everlasting light, and the days of thy mourning shall be ended.
Modern English
Your sun will not go down any more, nor will your moon withdraw itself; for Yahweh will be your everlasting light, and the days of your mourning will end.
