What has archaeology found about early Christians who fled Jerusalem?

Les teaches that archaeological digging has shown that many Jewish believers fled Jerusalem because of Saul's and other religious persecutions. They migrated up to the area of Galilee, and archaeologists have now found a community that identifies them as Jews who had been followers of Christ. Evidently some went as far as Damascus. Les also explains that Saul was not only a religious zealot but was motivated by money, profiting in the Jews' religion, and he notes that religious headquarters often hold tremendous wealth drawn from lower levels.
