'In the Light' in the Bible

What I say to you in darkness speak in the light, and what ye hear in the ear preach upon the houses.

And Peter followed him at a distance, till he was within the court of the high priest's palace; and he was sitting with the officers and warming himself in the light of the fire.

therefore whatever ye have said in the darkness shall be heard in the light, and what ye have spoken in the ear in chambers shall be proclaimed upon the housetops.

While ye have the light, believe in the light, that ye may become sons of light. Jesus said these things, and going away hid himself from them.

But if we walk in the light as he is in the light, we have fellowship with one another, and the blood of Jesus Christ his Son cleanses us from all sin.

He who says he is in the light, and hates his brother, is in the darkness until now.
