(Mishnah): The following are vows of Ones. Shimon made Reuven vow that he will eat by him. Reuven (was unable to because he) or his son fell ill, or he could not cross the river. These are vows of Ones.

(Gemara) Implied question - inference: It is because he fell ill, but if he did not fall ill, no. (Why can't he say, I vowed only for my honor?)

Answer #1 (R. Yirmeyah): Our Mishnah is R. Meir, for [if one said 'you may not benefit from me if you do not take for your children (from me) a Kor of wheat... He can say, 'you vowed only for my honor. This is my honor (that I not take).] R. Meir says, he is forbidden until he gives.

Answer #2 (R. Yosah): Why don't you explain it like everyone, like R. Ze'ira said, that they argue Stam?

Question: What is the case?

If [the Madir] says '[I vowed] for my honor', and the Mudar says '[you vowed] for my honor', all agree that he is forbidden!

If [the Mudar] says 'for my honor', and the Madir says 'for your honor', all agree that he is permitted!

Answer: (R. Heila): [They argue about Stam, when they do not speak. Chachamim hold] is it the way of a person to say to his friend [I vowed] for my honor?! (We assume that it was for the recipient's honor. We explained this like PNEI MOSHE.)
