How To Study the Bible

I found the following question, from http://www.lipanhousechurch.org/DOCTRINES/BibleStudy2a.html, most interesting.

When Paul and Silas were forced to leave Thessalonica, they came to Berea where they found Jews "of more noble character than the Thessalonians, for they received the message with great eagerness and examined the Scriptures every day to see if what Paul said was true," (Acts 17:11).

Question, what Bible study method did the Jewish Bereans use?

The reason I found this so interesting is because I misread the question. The question I found myself asking was:

Question: What Bible did the Jewish Bereans study for their answers?

In fact, when Jesus needed scriptural authority for such doctrines as marriage and divorce, what Bible did He use?

What Bible did Peter use when teaching the crowds the Gospel in Acts 2? What Bible did Paul use when teaching that both Jew and Gentile are sinners in Romans 3, or when teaching that each Christian has his own God-given gift in Ephesians 4? What Bible did James use when teaching about the efficacy of prayer in James 5?

Answer: The early church and her founder and her not-yet-Christian students, such as the Bereans, turned to the Tanakh ("Old Testament") as their source of authority for much of the church's doctrine. We do ourselves and the church a disservice when we ignore and remain ignorant of the first century church's Bible.
