Jesus is talking to a group of people about what they as individuals should or should not do. The instances of "you" and "your" are plural. (See: [[rc://en/ta/man/jit/figs-you]])
Jesus uses a question to teach the people. Alternate translation: "then your Father in heaven will most certainly give ... him." (See: [[rc://en/ta/man/jit/figs-rquestion]])
