Talmud sur Rois 2 8:7

It is written²⁸³2K. 8:7.: Elisha came to Damascus when Ben-Hadad the king of Aram was sick. What did he come to do there? He went to bring back Geḥazi but found him absolutely impure²⁸⁴Most rules of skin-disease (Lev.13:1–46) define two stages of the diagnosis. In the first one, the sufferer is quarantined (מֻסְגָּר). If he be found pure, a simple immersion in water will make him ritually pure. But if he was found impure after quarantine, he is absolutely impure and can regain purity only by the elaborate ceremony described in Lev. 14. For an inhabitant of the Northern kingdom, this would present almost insurmountable difficulties. (Naˋaman as a Gentile did not need any ceremony.) Elisha is faulted for not helping Gehazi to repent and regain his purity.. From here that one should push away with one’s left hand but bring back close with one’s right. Rebbi Joḥanan said, the stranger should not stay outside overnight; my doors I opened for the guest²⁸⁵Job 31:32.. From here that one should push away with one’s left hand but bring back close with one’s right. Not as Elisha did who pushed Geḥazi away with both hands. Elisha was sick with two sicknesses²⁸⁶In the Babli 107b: three sicknesses; the two mentioned here and an additional one for sending the bears against the children. In 2K. 13:14 it is mentioned that Elisha fell ill “with the sickness which would cause his death”. This implies that it was not his only sickness; he must have been sick at least twice.. One in the ways of the world, and one because he pushed Geḥazi away.
