Moses answered, “What if they do not believe me or listen to me and say, ‘The Lord did not appear to you’?” Then the Lord said to him, “What is that in your hand?” “A staff,” he replied. The Lord said, “Throw it on the ground.” Moses threw it on the ground and it became a snake, and he ran from it. Then the Lord said to him, “Reach out your hand and take it by the tail.” So Moses reached out and took hold of the snake and it turned back into a staff in his hand. “This,” said the Lord , “is so that they may believe that the Lord , the God of their fathers—the God of Abraham, the God of Isaac and the God of Jacob—has appeared to you.” Then the Lord said, “Put your hand inside your cloak.” So Moses put his hand into his cloak, and when he took it out, the skin was leprous —it had become as white as snow. “Now put it back into your cloak,” he said. So Moses put his hand back into his cloak, and when he took it out, it was restored, like the rest of his flesh. Then the Lord said, “If they do not believe you or pay attention to the first sign, they may believe the second. But if they do not believe these two signs or listen to you, take some water from the Nile and pour it on the dry ground. The water you take from the river will become blood on the ground.”
Exodus 4:1-9 NIV
The weight of Moses’s calling was taking a toll on him. How possible was it for people to believe that he had been called and sent by God? God knew the stubbornness in their hearts. So He gave Moses some signs to use when taken to task about his calling. These were not ordinary signs. They were miraculous signs. This is the first time in scripture (or one of the first times) we witness miracles being done. In fact God Himself instructs Moses to perform them. Why? Because of the people’s unbelief. They were not stand alone acts performed but were meant to point unbelieving people to God. When Moses threw his staff on the ground, it transformed into a serpent. The serpent was used in Genesis to symbolise the devil. God instructed him to pick it up using the tail. Interesting! Snakes are handled using their heads. But a frightened Moses, instructed by God picked the snake from its tail for it to reconvert to a staff. This God we serve is One who has conquered evil. Evil (the snake) is subdued before Him. But secondly, Moses is told to put his hand in his cloak after which it became leprous. Upon returning it back and sticking it out again it got healed. Our God heals all our diseases and infirmities. Lastly, God instructs Moses to perform another sign if people persist in their unbelief. He instructs him that he should pick Nile waters and pour them to the ground upon which they’ll convert into blood. The Nile was and still is Egypt’s lifeline. God would show Himself all powerful by being able to destroy what a great nation like Egypt depended on. By doing this, He would show His greatness. But why blood? Blood is a symbol of a covenant. God will be fulfilling the covenant He made to His servants Abraham, Isaac and Jacob. What stands out of this entire instruction is God’s love for His people. As He sent Moses, He wanted them to know without a shadow of doubt that He had sent him. God reveals Himself clearly to us at all times.
