In this parable, Jotham describes the trees and the vine as doing things that humans do. (See: [[rc://en/ta/man/translate/figs-parables]] and [[rc://en/ta/man/translate/figs-personification]])
The vine is asking this question to refuse to be king. This question can be expressed as a statement. AT: "I will not give up my new wine ... over the other trees." (See: [[rc://en/ta/man/translate/figs-rquestion]])
