And it came between the camp of the Egyptians and the camp of Israel; and it was a cloud and darkness to them, but it gave light by night to these: so that the one came not near the other all the night.
He made darkness his secret place; his pavilion round about him were dark waters and thick clouds of the skies.
But the path of the just is as the shining light, that shineth more and more unto the perfect day.
The way of the wicked is as darkness: they know not at what they stumble.
And he shall be for a sanctuary; but for a stone of stumbling and for a rock of offence to both the houses of Israel, for a gin and for a snare to the inhabitants of Jerusalem.
2 Corinthians 2:15
For we are unto God a sweet savour of Christ, in them that are saved, and in them that perish:
2 Corinthians 2:16
To the one we are the savour of death unto death; and to the other the savour of life unto life. And who is sufficient for these things?
