God reiterated His instructions to Moses to speak to Pharaoh and command him to let the people of God go. He protested again, and again God said that Aaron would be his prophet. He also told Moses that he would harden Pharaoh’s heart and prevent him from letting the Israelites go. He would then force Pharaoh to let them go by showing great signs to Egypt. So Moses and Aaron obeyed the Lord. Even as 80-somethings, they obeyed God and fulfilled their destiny.
Moses and Aaron went before Pharaoh, and when he asked for a sign, Aaron threw down his rod and it became a serpent. When this happened, Pharaoh’s sorcerers did the same thing. The interesting thing, though, is that Aaron’s rod ate all the other snakes, and it was a miraculous thing. However, Pharaoh’s heart was hardened.
When God sends you to do something, He will equip you and He will accompany you. You will not go alone! Trust God in everything, and walk with Him. Even when hearts are hardened, God can deliver His own!
