And Elisha said to Gehazi, Gird up your loins, and take my staff in your hand, and go: if you meet any man, you shall not greet him, and if a man greet you, you shall not answer him; and you shall lay my staff on the child's face.

And Gehazi went on before her, and laid his staff on the child's face; but there was neither voice nor any hearing. So he returned to meet him, and told him, saying, The child has not awakened.
