Yahweh uses a question for emphasis. Here "mother" refers to the city of Zion. This means that Yahweh did not send the people of Zion away like a man who decides to divorce his wife. (See: rc://en/ta/man/translate/figs-metaphor and rc://en/ta/man/translate/figs-rquestion)

And to which of my creditors did I sell you?
