Jesus uses a question to help the apostles remember how well the people provided for them as they traveled. Though this is a rhetorical question and Jesus is not asking for information, you should translate it as a question unless only a statement would cause the disciples to reply that they had lacked nothing. (See: [[rc://en/ta/man/translate/figs-rquestion]])
It may be helpful to some audiences to include more about the conversation. Alternate translation: "We did not lack anything" or "We had everything we needed" (See: [[rc://en/ta/man/translate/figs-ellipsis]])
