worthwhile to read his biography written by his daughter mrs. esther shulamis [steif] bleier published by feldheim. Amazing Tzadik and Godal!
Mentioned in the above biography is a story about a young man who was called to serve in the army. He went to Rav Yonasan zt”l who give him an incantation to say before he saw the doctor. When he said , the goats in the slaughter house are fatter than me (Tractate Megilla), he became a lepper, so the doctor through him out in order not to get infected. When he left and went out to the steet, it disappeared.
I love that story, laskern. Thank you for sharing it.
The story above is mentioned in many places just that it does not say that he became a lepper only that he developed a swelling on his hand that released puss which was considered contagious.
Tomorrow 9th Elul will be his 61st Yohr Tzeit.
