"Moses Leaving to Egypt"

The painting shows Moses (dressed in yellow and green as in the other frescoes of the cycle) leaving for Egypt, after he had been exiled from Midian, with Zipporah to his right. In the center, an angel asks him to circumcise his son Eliezer (scene on the right), as a sign of the alliance between Yahweh and the Israelites. The baptism, depicted on another fresco, was in fact considered by several early Christian writers, including Augustine, as a kind of "spiritual circumcision". The ceremony is on the right, and includes Zipporah.

In the right background Moses and Zipporah are greeting Jethro before leaving. Natural elements include the hill landscape in the background, characterized by thin trees (including a palm, a symbol of Christian sacrifice), and the birds: two of them are mating, an allusion to the renovations cycles of the nature. On the left background is a group of shepherds.
