To paraphrase:

'I pursued my enemies and crushed them. I did not turn back until they were destroyed' 2 Samuel 22 38
James Tarvelli is my enemy. You are not. I implore you to keep it that way.
~Iykos

It's basically a warning to get out while she still can, because he intends to destroy James and all of his men
