The repetition of the pronoun they, they is an emphatic form. Jerusalem is using the repetition for emphasis to express the depth of betrayal. If it would be clearer for your readers, you could express the emphasis with a single phrase. Alternate translation: [they completely deceived me]

Jerusalem is referring to death in a polite way by using the word expired. Depending on what is helpful for your readers, you could use a polite way of referring to this in your language, or you could state this plainly. Alternate translation: [passed away] or [died]
