The Return of the King
"A Halfling," answered Gandalf. "Nay, not the one that was spoken of," he added seeing the wonder in the men's faces. "Not he, yet one of his kindred."
"Yes, and one who journeyed with him," said Pippin. "And Boromir of your City was with us, and he saved me in the snows of the North, and at last he was slain defending me from many foes."
"Peace!" said Gandalf. "The news of that grief should have been told first to the father." (5.19-21)
Be careful of your words, Master Peregrin! This is no time for hobbit pertness. Théoden is a kindly old man. Denethor is of another sort, proud and subtle, a man of far greater lineage and power, though he is not called a king. But he will speak most to you, and question you much, since you can tell him of his son Boromir. He loved him greatly: too much perhaps, and the more so because they were unlike. But under cover of this love he will think it easier to learn what he wishes from you rather than from me. Do not tell him more than you need, and leave quiet the matter of Frodo's errand. (5.1.44)
Filled suddenly with love for this old man, he knelt on one knee, and took his hand and kissed it. "May I lay the sword of Meriadoc of the Shire on your lap, Théoden King?" he cried. "Receive my service, if you will!"
"Gladly will I take it," said the king; and laying his long old hands upon the brown hair of the hobbit, he blessed him. "Rise now, Meriadoc, esquire of Rohan of the household of Meduseld!" he said. "Take your sword and bear it unto good fortune!"
"As a father you shall be to me," said Merry.
"For a little while," said Théoden. (5.2.49-52)
