Create an illustration of a scene from the Biblical passage Mark 11:27 - 'And they come again to Jerusalem: and as he was walking in the temple, there come to him the chief priests, and the scribes, and the elders,'. The illustration should be detailed and vibrant, resembling a blend of mid-century art and mosaic work. Capture the spiritual and historic atmosphere of the scene, with the central figure walking in the temple, approached by the chief priests, scribes, and elders. These figures should have an array of different descents, including but not limited to Middle-Eastern, South Asian and Caucasian, to represent the diversity of the ancient world. Please prioritize the usage of sharp lines and bold colours, similar to digital art.
