A watercolor painting depicting the biblical event described in Matthew 8:13. The scene shows a Roman centurion, humbly dressed, speaking to a man portrayed as Jesus, both standing in an ancient Middle-Eastern streetscape. In the distant background, one can see the silhouette of a servant, symbolizing the healing that's about to take place.
