How there came a voice which charged Sir Bors to touch him not, and of a cloud that came between them.
And then he heard a voice that said: Flee Bors, and touch him not, or else thou shalt slay him. Right so alighted a cloud betwixt them in likeness of a fire and a marvellous flame, that both their two shields brent. Then were they sore afraid, that they fell both to the earth, and lay there a great while in a swoon. And when they came to themself, Bors saw that his brother had no harm; then he held up both his hands, for he dread God had taken vengeance upon him. With that he heard a voice say: Bors, go hence, and bear thy brother no longer fellowship, but take thy way anon right to the sea, for Sir Percivale abideth thee there. Then he said to his brother: Fair sweet brother, forgive me for God’s love all that I have trespassed unto you. Then he answered: God forgive it thee and I do gladly.
