He went then to the last of the seven doors and asked who was at it. “No friend of yours,” they said, “but it is Finn, son of Cumhal, and four hundred paid fighting men along with him; and if you will come out to us we will make opened marrow of you.” “I give you my word, Finn,” said Diarmuid, “that the door you are at yourself is the first door I will pass out of.”
When Finn heard that, he warned his battalions on pain of lasting death not to let Diarmuid past them unknown. But when Diarmuid heard what he said, he rose on the staves of his spears and he went with a very high, light leap on far beyond Finn and his people, without their knowledge. He looked back at them then, and called out that he had gone past them, and he put his shield on his back and went straight on towards the west, and it was not long before he was out of sight of Finn and the Fianna. Then when he did not see any one coming after him, he turned back to where he saw Angus and Grania going out of the wood, and he followed on their track till he came to Ros-da-Shoileach.
He found Angus and Grania there in a sheltered, well-lighted cabin, and a great blazing fire kindled in it, and the half of a wild boar on spits. Diarmuid greeted them, and the life of Grania all to went out of her with joy before him.
Diarmuid told them his news from beginning to end, and they ate their share that night, and they went to sleep till the coming of the day and of the full light on the morrow. And Angus rose up early, and he said to Diarmuid: “I am going from you now, grandson of Duibhne; and I leave this advice with you,” he said, “not to go into a tree with one trunk, and you flying before Finn, and not to be going into a cave of the earth that has but one door, and not to be going to an island of the sea that has but one harbour. And in whatever place you cook your share of food,” he said, “do not eat it there; and in whatever place you eat it, do not lie down there; and in whatever place you lie down, do not rise up there on the morrow.” He said farewell to them after that, and went his way.
