We’ll give another example of a person who makes an oath and violates it a number of times, and how we deal with it. The Mishnah says: A person swears that he is not going to eat. He eats three different types of bread: wheat bread, barley bread, and spelt bread, and he has forgotten that he made the oath. We say that he is obligated to bring only one korban chatat oleh veyored (variable sin offering), because he violated only one oath. The oath he made was not to eat, and during one single period of forgetfulness, he ate several different things. So we say he only has to bring one korban (offering) for that eating during that period of forgetfulness.
But if he swears that he is not going to eat wheat bread, barley bread, or spelt bread, and he eats all three of them, he is obligated to bring a separate korban for each and every one of them. He is considered to have made three different oaths, and he violated all three of them by the fact that he said “bread” three different times. It shows that he meant to make three different oaths, and therefore he would have to bring three different korbanot.
