Mephibosheth speaks of how his relatives had deserved to be executed as if they had already been executed and were dead. Alternate translation: "all my father's house deserved for my master the king to order them to be executed" (See: [[rc://en/ta/man/jit/figs-metaphor]])
Mephibosheth uses this rhetorical question to emphasize that he has no right to request anything from the king. This can be written as a statement. Alternate translation: "Therefore, I have no right to ask the king to do anything else for me." (See: [[rc://en/ta/man/jit/figs-rquestion]])
