Create a digital representation of an ancient scene based on the verse from Exodus 36:20. The focal point of the image should be a collection of boards made from shittim wood, standing upright- these are used for the construction of the tabernacle in biblical times. Make sure the wood exhibits a rich texture and the chiseled marks of manual labor. The backdrop should subtly hint at a desert locale, a reference to the wanderings of the ancient Israelites. Use contrasting shadows and light to impart a sense of sacred significance to these simple wood planks.
