What does it mean to be like the Bereans?

The brothers immediately sent Paul and Silas away by night to Berea, and when they arrived they went into the Jewish synagogue.

Now these Jews were more noble than those in Thessalonica; @they received the word with all eagerness,
@examining the Scriptures daily to see if these things were so.    Many of them therefore believed,
with not a few Greek women of high standing as well as men.
Acts 17:10-12 ESV
