Give glory to the Lord your God, before darkness falls, and before your feet stumble on the darkened mountains. You will expect light, but he will turn it into the shadow of death and into utter darkness.
For this reason, their way will be like a slippery path in the dark. For they will be impelled forward, and they will fall in it. For I will bring evils over them, in the year of their visitation, says the Lord.
Therefore, Jesus said to them: "For a brief time, the Light is among you. Walk while you have the Light, so that the darkness may not overtake you. But whoever walks in darkness does not know where is he going.
But whoever hates his brother is in the darkness, and in darkness he walks, and he does not know where he is going. For the darkness has blinded his eyes.
