Midrash sur Rois 2 4:31

Now as for Gehazi, the matter was laughable in his eyes, and to every man whom he met || he said: Dost thou believe that this staff will bring the dead to life? Therefore he did not succeed until (Elisha) went on foot and put his face upon the face (of the child), and his eyes upon his eyes, and his hands upon his hands, and he began to pray before the Holy One, blessed be He: Sovereign of all the worlds ! Just as Thou didst perform miracles by the hand of Elijah, my master, and brought the dead to life, likewise let this child live; and He was entreated of him, as it is said, "Then he returned, and walked in the house once to and fro; and went up, and stretched himself upon him" (2 Kings 4:35); "and the child sneezed seven times" (ibid.).
