There is [a case in which] one plows a fur-row and is liable on its account for eight negative commandments: One who plows with an ox and a donkey which are consecrated, with kilayim in a vineyard, and during the Sabbatical year, and on a Festival, and [he is] a Kohen and a nazir in a tumah-contaminated place. Chananya ben Chachinai says: Also one who was wearing ki-la-yim. They said to him: This is not for that reason. He replied to them: Neither is nazir for that reason.
