Around the time of Jesus two rival בת מדרשים, or study houses seem to come up a lot in tradition. One is the House of Hillel and One is the House of Shammai. Both give us a window into developing rabbinic thinking and discussions pretty close to Jesus and Paul as well. They are just good to have in your back pocket as you read the gospels, Acts, and early Christian Letters because they help you understand broader discussions about how ancient authors pull forward the text of the Bible into rabbinic and early Christian thought…which are more similar than different.
