תלמוד על פסחים 147:10

It was stated⁴Tosephta 5:8; Babli 74a. in the name of Rebbi Jehudah: He roasts it on a metal spit. They said to him, is it not hot and heats⁵Then the inner parts of the lamb are cooked by the heat of the spit, not roasted by the fire outside; cf. Halakhah 2.? He said to them, just as the wooden one is not burned, so the metal one does not heat. They said to him, wood is not comparable to metal, for wood, if it is hot somewhere, is not hot everywhere, but metal if hot somewhere is hot everywhere.
