Create a digital art interpretation of a historical scriptural scene involving an important religious figure imparting wisdom in a biblical context. Specifically, illustrate the verse from Galatians 5:2: 'Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing.' Showcase a depiction of the main figure, in traditional biblical attire, communicating this message to a diverse crowd. The setting should reflect an ancient Middle Eastern environment, complete with rustic buildings and an expansive desert landscape in the background. Please include scrolls or other period-specific artifacts to reinforce the historical context.
