Give glory to the LORD your God, before he cause darkness, and before your feet stumble on the dark mountains, and, while you look for light, he turn it into the shadow of death, and make it gross darkness.
Why their way shall be to them as slippery ways in the darkness: they shall be driven on, and fall therein: for I will bring evil on them, even the year of their visitation, said the LORD.
Then Jesus said to them, Yet a little while is the light with you. Walk while you have the light, lest darkness come on you: for he that walks in darkness knows not where he goes.
