2 Kings 2:9-10

9After they had crossed the river, Elijah said to Elisha, ‘The Lord will soon take me away from you. What do you want me to do for you before that happens?’ Elisha replied, ‘Please let me have twice as much of your spirit.’

10Elijah said, ‘You have asked a difficult thing. But watch carefully when God takes me from you. If you see it happen, you will receive that spirit. If you do not see me, you will not receive it.’
