# Which of you by being anxious can add a cubit to his lifespan? Jesus uses a question to teach his disciples. Alternate translation: "None of you can make your life any longer by being anxious!" (See: [[rc://en/ta/man/jit/figs-rquestion]]) # add a cubit to his lifespan This is a metaphor because a cubit is a measure of length rather than of time. The image is of a person's life stretched out as if it were a board, a rope, or some other physical object. (See: [[rc://en/ta/man/jit/figs-metaphor]]) # cubit the length from a man's elbow to the end of his fingers
