Moses had to lead the people of Israel through the desert to the Promised Land. God ordered him to appoint 70 advisors to help him with this formidable task. In 1737, Jacob de Wit was commissioned to do a painting of this story by the Amsterdam city council. This was a council of 36 wise men who acted as advisors to the four ruling mayors. The canvas covers the entire back wall of the former council chamber and measures 5 by 13 metres – one of the largest canvases in the Netherlands.
