Halacha that a woman should stay in house?

Tehilim (45:14):  כָּל כְּבוּדָּה בַת מֶלֶךְ פְּנִימָה מִמִּשְׁבְּצוֹת זָהָב לְבוּשָׁהּ
 The daughter of the king is all glorious within; her clothing is of embroidered gold.

Rav Menashe Klein (9:250): Question: Concerning the halacha principle that a Jewish woman is considered a princess and therefore it is more respectful for that status that she should remain in the home (kavod bas melech penima) – is it preferable that a wife leave the home for the sake of her husband to a place of immorality [in order to earn a living or other purposes]. Answer: It is difficult to give a clear written response to this question. That is because in modern time this principle that it is best that a Jewish woman should stay in the home is almost nonexistent – because of our many sins. If a woman does remain in her home and doesn’t go out for any reason– even if it causes her husband to lose Torah study - then this is definitely an example of the principle. Traditionally a woman did not go out of her house. However after the Holocaust (because of our many sins) – when we find ourselves a small minority amongst the nations of the world and earning a livelihood is difficult – it has become normative practice for women to leave their homes. However in places outside the home there is the possibility of immorality and no protection against sexual sins – therefore it depends on the nature of the society and the characteristics of the woman. In particular whether she would in fact remain in the house all day if she had the opportunity. (See what I wrote in Mishne Torah 4:125) concerning sending Beis Yaakov girls out to collect money for charity.) First we need to clarify whether we actually rule that this principle is the halacha. It seems that in fact that it is a dispute amongst the poskim - as we see from Gittin 12 that apparently we don’t follow such a principle. Similarly Mahari Bruno (#242) was asked regarding a maid servant who did not want to leave the home to do the shopping because of this principle. He responded that we don’t rule in accord with this principle. In contrast we see in Yevamos (77a) that this principle is cited as halacha [from the fact that Amonite and Moabite women were not punished for failing to provide the Jews with bread and water - since all respectable woman remain in the home] . The Nimukei Yosef say there that the principle is halacha because all Jews are considered royalty. Shulchan Aruch (E.H 4) also rules like Yevamos (77a). See the Levush. Consequently we seem to have contradictory evidence as to whether it is halacha. Furthermore in Shabbos (111a), Rav Shimon says that all Jews are royalty and that is the halacha. On the other hand the Ran says that the Rif says that the halacha that all Jews are not considered royalty. However the BeHag and Rabbeinu Chananel rule like Rav Shimon...Rashi (Shabbos 59) writes that all Jews are royalty. Similarly in Mishna Berachos (1:2) says that they are royalty. However Rabbeinu Yona says normally they are not considered royalty but here we do. In my chidushim I write that there are three different circumstances. In truth there is no question that the honor of a princess is to stay in the home. However in spite of that, we find with Ruth that she did go out to gather grain amongst the other harvesters – and she is praised for doing so.  But look at Rashi and the interpretations of Chazal that say when she went out she sought out the company of proper people. If so we can state that when a person does need to go out of the home this principle requires finding a place where there are proper people. In such circumstances there is no prohibition.

Eiruvin(100b): She is wrapped like a mourner, banished from all man and imprisoned in a jail [because the honor of the king’s daughter is within – Rashi] 

Bereishis Rabba (8:12): R. Johanan b. Berokah said: Concerning both man and woman it says,  AND GOD BLESSED THEM, etc.2 ‘We-kibshah’ (and subdue her) is written: the man must master his wife, that she go not out into the market place, tor every woman who goes out into the market place will eventually come to grief. Whence do we know it? From Dinah, as it is written, And Dinah... went out, etc. (Gen. XXXIV, 1). R. Isaac said in R. Hanina's name: The law is as stated by R. Johanan b. Berokah.

נשאלתי השוכר משרתת אשה או נערה בתולה וראובן שולח אותה על השוק ובבתי הגויים יחידית והמשרתת אומרת השכרתני לשרת כדרך המשרתות בבית ולא כדרך האנשים היוצאים בחוץ:

והשבתי כן הנשים דוברות. אין ראובן יכול לכופן ליכנס יחידית בבתי הגויים ואף יש איסור בדבר משום יחוד, ואף במקום שרבים רגילים ליכנס שם נהי דאיסור ליכא מ"מ אינו יכול לכופן, דיש נשים צנועות נוהגות בצניעות או יראות מרוב שנאה שלא יטילו עליה שם רע או כה"ג, אמנם על השוק בגילוי, רגילות הנשים לילך אבל הבתולות אין דרכן לצאת לשוק ואינו יכול לכוף, ונ"ל דאף איסור יש בדבר שנאמר לא תצא כצאת העבדים. וכתב בפי' התורה לר' יעקב בר אשר ז"ל שנקרא נזיר וז"ל י"מ שלא ישלחנה בחוץ לעשות מלאכתו אלא תשמשנו בבית, עכ"ל והתורה בבתולה קאי ובבתולה מיירי אבל נשים לא כדפירש', אף על גב דכתיב כל כבודה בת מלך פנימה מ"מ אשכחן בפ"ק דגיטין (יב א) דשכיח כדאמרינן מהו דתימא כל כבודה בת מלך פנימה קמ"ל, ובפרק המוצא תפלין (ערובין ק ב) אמר גבי יו"ד קללות שנתקללה חוה וחבושה בבית האסורים ואידך הנך שבח הוא לה דכתיב כל כבודה בת מלך פנימה, והטעם כל ישראל בני מלכים הם. ולית הלכתא הכי, דאמרינן בפ' המקב' (ב"מ קיג א) אמר אביי כולהו ס"ל כל ישראל בני מלכים הם, וכל היכא דאמר אביי הכי כולהו בחד שיטה לית הלכתא כחד מינייהו, כדפסק האשירי בכמה דוכתין, ואף על גב דבפ' ח' שרצים (שבת קכו ב) פסק רב הלכתא כרשב"ג דאמר הכי מפרש התם הלכתא כוותיה ולא מטעמיה ע"ש, וכן פסק האשירי בהדי' בפ' מפנין
