Bread is a food that people in Israel commonly ate. If people in your community do not know what bread is, you may translate it with a more general expression for food. Alternate translation: "give you some food ... give you as much food" (See: [[rc://en/ta/man/jit/translate-unknown]])
Jesus addresses the disciples as if they were the ones asking for bread. Alternate translation: "give bread to him because he is ... his ... him ... he needs"
The phrase can be reworded to eliminate the abstract noun "persistence." Alternate translation: "because you persist shamelessly" or "because you boldly continue to ask him" (See: [[rc://en/ta/man/jit/figs-abstractnouns]])
