“Will closed his eyes. He could not hear Jem go, not anymore; he did not want to know the moment when he left and Will was alone, did now want to know when his first day as a Shawdowhunter without a parabatai truly began. And if the place over his heart, where his parabatai rune had been, flared up with a sudden burning pain as the door closed behind Jem, Will told himself it was only a stray ember from the fire.”

“Whither thou goest, I will go;
Where thou diest, will I die
And there will I be buried:
The Angel do so to me, and more also,
If aught but death part thee and me.”
― Cassandra Clare, Clockwork Prince

“Entreat me not to leave thee, or to return from following after thee - for whither thou goest, I will go, and where thou lodgest, I will lodge. Thy people shall be my people, and thy God my God. Where thou diest, will I die, and there will I be buried. The Angel do so to me, and more also, if aught but death part thee and me.”

“You swore to stay with me,” he said. “When we made our oath, as parabatai. Our souls are knit. We are one person, James.”
“We are two people,” said Jem.
“Two people with a covenant between us.”
Will knew he sounded like a child, but he could not help it.
“A covenant that says you must not go where I cannot come with you.”
“Until death,” Jem replied gently.
“Those are the words of the oath. ‘Until
aught but death part thee and me.’ Someday, Will, I will go where none can
follow me, and I think it will be sooner rather than later.”
