Miscellanies 1.23.157

Then the Egyptians, often without understanding, were often warned; and the Hebrews were spectators of the evils that others suffered, learning the power of God without danger. And further the Egyptians, not accepting by hearing the effects of his power, disbelieving through folly, then, as it is said, “the fools knew it when it was done.” And afterward, when the Hebrews went out, they departed carrying off much booty from the Egyptians, not from love of money, as the accusers say (for God did not persuade them to desire what belonged to others), but first receiving a necessary wage for the service they had rendered the Egyptians throughout the whole time, and then in some way avenging themselves by grieving the money-loving Egyptians in return, by carrying off the booty, as they had grieved the Hebrews by enslaving them. Whether, then, one should say that this took place as in war, they thought it right to take the goods of their enemies by the law of the victors, as the stronger over the weaker (and the cause of the war was just: the Hebrews came as suppliants to the Egyptians because of famine, and they enslaved the strangers and forced them to serve them like captives, not even paying them a wage); or as in peace, they took the booty as a wage from those unwilling to pay, who had for a long time not paid it but defrauded them.
