Reddit mentions of Understanding Second Temple and Rabbinic Judaism

If you want scholarly articles, just search the subject you're interested in at JSTOR, and I can recommend books based on some of them, but for quick answers:

>How did the institution of having concubines work?

Live in girlfriend with no legal strings attached.

>Is it a translation issue into English, using the common English terms for those particular constellations?

Yes. For the most part, constellations are similar across cultures as no matter where you are in the same hemosphere, you will see the same basic shapes.

>Aren't interfaith marriages against Deuteronomy 7:3 (which Moses is traditionally held to have written)?

They are, which is part of Miriam's accusation against Moses in Numbers 12, but the instruction had not yet been given at the time Moses married Zipporah, and the general understanding is that everyone present at Mt. Sinai accepted the Torah's instructions at that point, so presumably Zipporah adopted her husband's religion when it became an official religion.

>Are there any good books or articles to read... [and your other questions]

Primary sources: Works by Josephus and Philo

Secondary Source: Understanding Second Temple and Rabbinic Judaism by Dr. Lawrence Schiffman and the center for online Jewish studies' surveys from several Jewish studies professors.

>Can and did these more modern rabbis radically change prior interpretations of the Tanakh?

Yes.
