Daf Yomi - Yoma 51 - Watch your Step!!

The Mishna states that the kohen gadol would walk between the two curtains as he entered the Kodesh Kodoshim. The space in between them was only one cubit foot. The Yerushalmi says that he would push out both curtains with his elbows as he walked through. The Pnei Moshe explains this by pointing out that in his right hand he was holding the pan with the hot coals and in his left hand was the ketores. He had to be extremely careful not to burn the peroches.
