And thou shalt decree a thing, and it shall be established unto thee; and light shall shine upon thy ways.
Light is sown for the righteous, and joy for the upright in heart.
Unto the upright there ariseth light in the darkness; he is gracious, and merciful, and righteous.
But the path of the righteous is as the shining light, going on and brightening until the day be fully come.
Then shall thy light break forth as the dawn, and thy health shall spring forth speedily; and thy righteousness shall go before thee, the glory of Jehovah shall be thy rearguard.
Thy sun shall no more go down, neither shall thy moon withdraw itself; for Jehovah shall be thine everlasting light, and the days of thy mourning shall be ended.
Again therefore Jesus spoke to them, saying, I am the light of the world; he that follows me shall not walk in darkness, but shall have the light of life.
1 John 2:10
He that loves his brother abides in light, and there is no occasion of stumbling in him.
