Aaron's Rod: KJV

  Aaron was Moses' brother who helped Moses when he was sent to the Pharaoh by the Lord. Aaron's rod was used to show the Pharaoh that God was the children of Israel's one true God. When the time came, Aaron threw down his rod in the sight of the Pharaoh and it turned into a snake. Yes, the magicians threw their rods down too, but it was the snake from Aaron's rod who swallowed up the others symbolizing God is mightier. To read about this go to Exodus 7:8-13.
  This same rod was used later to bring about the first three plagues and it was used to bring the water from the rock at Horeb and the rock at Kadesh. Read about the rocks springing forth water in Exodus 17 and Numbers 20. 
  In Numbers chapter 17, the Bible tells us that the head of each tribe of Israel put his name on a rod to decide who would come before God as priests in the tabernacle. When the rods were checked the next morning, Aaron's rod had blossomed and bore almonds. This was God's sign that Aaron's house would serve in the tabernacle. In Hebrews chapter 9 verse 4, it tells us that Aaron's rod was placed in the ark of the covenant.
