Tze'enah Ure'enah
Bahya writes. The king of Egypt had a dispute with the king of Ethiopia. The king of Egypt said to the king of Ethiopia: you have taken away my land. The king of Ethiopia said the same. However, when the frogs came to the land of Egypt, they saw how far the land of Egypt extended. There were frogs in the whole land of Egypt up to the border of the land of Ethiopia. From then on, there was peace between the two kings.21Bahya, Exodus, 7:27.
