Exodus 4, 1 – 5 „But, objected Moses, suppose they do not believe me or listen to me? For they may say, ‘The LORD did not appear to you.’ 2The LORD said to him: What is in your hand? A staff, he answered. 3God said: Throw it on the ground. So he threw it on the ground and it became a snake, and Moses backed away from it. 4Then the LORD said to Moses: Now stretch out your hand and take hold of its tail. So he stretched out his hand and took hold of it, and it became a staff in his hand. 5That is so they will believe that the LORD, the God of their ancestors, the God of Abraham, the God of Isaac, and the God of Jacob, did appear to you”.
