Exodus 4:29-31

Young's Literal Translation

²⁹ And Moses goeth -- Aaron also -- and they gather all the elders of the sons of Israel,

³⁰ and Aaron speaketh all the words which Jehovah hath spoken unto Moses, and doth the signs before the eyes of the people;

³¹ and the people believe when they hear that Jehovah hath looked after the sons of Israel, and that He hath seen their affliction; and they bow and do obeisance.
