Nedarim

A woman once came before Rabbi and said, 'Rabbi! I set a table before my husband, but he overturned it.' Rabbi replied: 'My daughter! the Torah hath permitted thee to him — what then can I do for thee?' A woman once came before Rab and complained. 'Rabbi! I set a table before my husband, but he overturned it.' Rab replied; Wherein does it differ from a fish? And that ye seek not after your own heart.  [Deducing] from this Rabbi taught: One may not drink out of one goblet and think of another.  Rabina said: This is necessary only when both are his wives. And I will purge out from among you the rebels, and them that transgress against me.  R. Levi said: This refers to children belonging to the following nine categories: children of fear,  of outrage, of a hated wife, one under a ban,  of a woman mistaken for another,  of strife,  of intoxication [during intercourse], of a mentally divorced wife,  of promiscuity, and of a brazen woman.  But that is not so: for did not R. Samuel b. Nahmani say in the name of R. Jonathan: One who is summoned to his marital duty by his wife will beget children such as were not to be found even in the generation of Moses? For it is said, Take you wise men, and understanding [and known among your tribes, and I will make them rulers over you];  and it is written, So I took the chiefs of your tribes, wise men and known  but 'understanding' is not mentioned.  But it is also written, Issachar is a large-boned ass;  whilst elsewhere it is written, And of the children of Issachar, which were men that had understanding of the titles?  — [It is virtuous] only when the wife ingratiates herself [with her husband].
