Why does the Torah add the 'Hei' in "ha'Teme'im"?
Torah Temimah (citing Chulin, 22b): It teaches us that the skin of Sheratzim is Metamei like the flesh. 1
Though from the word "Eileh" we learn that it only pertains to the five in the previous Pasuk (with the exception of the Tinshemes (the mole, since it is thick-skinned) and not to the three in Pasuk 29. (See Torah Temimah).
