Esias 60:20

20 For the sun shall no more set, nor shall the moon be eclipsed; for the Lord shall be thine everlasting light, and the days of thy mourning shall be completed.

Esias 60:20 In-Context

18 And injustice shall no more be heard in thy land, nor destruction nor misery in thy coasts; but thy walls shall be called Salvation, and thy gates Sculptured Work.
19 And thou shalt no more have the sun for a light by day, nor shall the rising of the moon lighten thy night; but the Lord shall be thine everlasting light, and God thy glory.
20 For the sun shall no more set, nor shall the moon be eclipsed; for the Lord shall be thine everlasting light, and the days of thy mourning shall be completed.
21 Thy people also shall be all righteous; they shall inherit the land for ever, preserving that which they have planted, the works of their hands, for glory.
22 The little one shall become thousands, and the least a great nation; I the Lord will gather them in time.
