Considering the Mishnaic משתה

The day on which one cuts one's beard or one's hair, the day that he came ashore from the sea, the day he was released from prison, or a gentile who made a drinking-event for his son, these are only forbidden for that day alone and only for that man.

If one finished harvesting [his olives] but intends to buy, or finished buying but intends to borrow, if mourning, a drinking-event, or something unavoidable occurred, even if zavim or zavot walk upon them, they remain pure.

There was an instance with Rabbi Akiva who made a drinking-event for his son, over which he opened each and every barrel.

Rabbi Meir says, "They made a parable from Rabban Gamliel's name: 'To what is the matter comparable? To two people who made a drinking-event in one city; one called the townspeople, but not the king, while the other called neither the king nor the townspeople.

Which of these two people should have a greater punishment?

The one who called the townspeople, but not the the king - that one should receive a greater punishment than the second person.'"

Rabbi Shimon, son of Elazar, says, "Jews who live outside of the land [of Israel] are gentiles with their purity.
"How so?
"A gentile who made a drinking-event for his son and went and invited all of the Jews in his city - even though they eat and drink their own, and their own waiter stands over them and serves them, they nonetheless serve idolatry, as it is said, '[Lest you make a covenant with the inhabitants of the land, and when they play the harlot after their gods and sacrifice to their gods] and one invites you, you eat of his sacrifices' (Ex. 34:15)."

One who says to his fellow, "Konam if I derive any benefit whatsoever from you, if you do not come and collect for your child a kor of wheat and two jugs of wine" - and an occasion of mourning, of a drinking-session, or there were rains, then it is permitted.

"And, if not, he is prohibited until he will find absolution for his view through the ruling of a sage," the words of Rabbi Meir.

And the Sages say, "Also: this one can annul his vow without consultation with a sage."
He may say to him, "Did you not speak only to do me honor? But this is what I deem to be honorable."

And, similarly, one who says to his fellow, "Konam if you derive benefit from me, if you do not come and give my son a kor of wheat and two jugs of wine."

If one was nagging his fellow to eat with during a drinking-session and said, "Konam be your house if I enter it" - during the drinking-session, he is prohibited from going in there. After the drinking-session, he is permitted to go in there.

Rabbi Yehudah says, "If one was nagging his fellow during the festival to eat with him, and said to him, 'Konam be your house if I enter it' - during the festival, he is prohibited from entering it; after the festival, he is permitted to enter it."

If one was nagging his fellow to eat with him during a drinking-session and said to him, "Konam be your house if I enter it." During the drinking-session, he is prohibited from going in there. After the drinking-session, he is permitted to go in there.

If he said "Konam be your house if I enter it" or "If I drink a single drop of cold water of yours" - he is permitted to enter his house and to wash him with cold water. But he is prohibited from eating or drinking with him.
