We are [Thine]. There is no word for "Thine" in Hebrew text. The Hebrew accent (disjunctive) leaves a solemn hiatus between the two clauses; as though, what Israel had become could not be expressed by words: "We are come to this Thou never barest rule over them"; implying an Ellipsis, to be supplied thus: "We are become [as they]".
they were not called by Thy name = Thy name was not called upon them.
