Study Guide Nazir 62 The Gemara brings several possibilities to extrapolate the words "a man who expresses" in the verse about valuations. Each possibility is partially rejected until Rav Ada bar Ahava brings a drasha that is not rejected. The Gemara brings several possibilities to extrapolate the words "a man who expresses" in the verse about the nazir. Each possibility is partially rejected until the braita is brought to show that we can derive from there the law that one can nullify one's vows. The Mishna teaches that there is a stringency by slaves regarding nezirut that is not true for women - one can nullify his wife's vows, but if he breaks the nezirut of his slave (i.e. forcing him to drink wine), when he is freed, the prohibitions will come into effect again. The Gemara brings a braita with the following question: Why is it even permitted for a master to force his slave to drink wine when he is a nazir but if the slave takes an oath or vow, one cannot force him to go against it? After two failed attempts to answer the question, Abaye understands the braita differently - that one can force a slave to not keep his nazirite vow, but vows and oaths one does not need to force one's slave not to keep, as a vow or oath of a Canaanite slave is not valid at all. If a slave has been freed, his nezirut is reinstated, but what if he ran away? Rabbi Meir and Rabbi Yossi disagree. What is their point of disagreement?
