2 Kings 2-5
Elisha asks Elijah for a double portion of his spirit, just before Elijah ascends to heaven.
I haven't counted recently, but remember 7 miracles of Elijah's recorded in Scripture.
Elisha performs 14.
The 14th is the resurrection of a man whose body touches Elisha's dead body, just as the final miracle will be the General Resurrection to life of all those who are united with Christ in His death.
