Nazir 9:5-Sotah 1:1
Nazir 9:5
Rabbi Nehorai said that the prophet Samuel was a nazir based on I Samuel 1:11 – “no morah (presumably meaning a razor) shall come upon his head.” We also see the word morah used regarding Samson (Judges 13:5); just as its use regarding Samson refers to being a nazir, so does its use regarding Samuel. Rabbi Yosi says that morah refers to flesh and blood, i.e., that Samuel would fear no human being. Rabbi Nehorai objected to this interpretation based on I Samuel 16:2, in which Samuel said, “How can I go? If Saul hears of it, he will kill me.” We see from this that Samuel did in fact fear human beings.
Sotah 1:1
Regarding a man who warns his wife against seclusion with a particular man, Rabbi Eliezer says he must warn her in front of two witnesses and he can make her go through the sotah process based on the testimony of one witness, or even based on his own testimony. Rabbi Yehoshua says that he must warn her in the presence of two witnesses and he can only make her go through the sotah process based on the testimony of two witnesses.
