Exodus 1:10

Any war - The Northeastern frontier was infested by the neighboring tribes, the Shasous of Egyptian monuments, and war was waged with Egypt by the confederated nations of Western Asia under the reigns of the successors of Amosis. These incursions were repulsed with extreme difficulty. In language, features, costume, and partly also in habits, the Israelites probably resembled those enemies of Egypt.

Out of the land - The Pharaohs apprehended the loss of revenue and power, which would result from the withdrawal of a peaceful and industrious race.
