Exodus 14:5 - Clarke's commentary and critical notes on the Bible

And it was told the king of Egypt that the people fled: and the heart of Pharaoh and of his servants was turned against the people, and they said, Why have we done this, that we have let Israel go from serving us? And it was told the king - that the people fled - Of their departure he could not be ignorant, because himself had given them liberty to depart: but the word fled here may be understood as implying that they had utterly left Egypt without any intention to return, which is probably what he did not expect, for he had only given them permission to go three days' journey into the wilderness, in order to sacrifice to Jehovah; but from the circumstances of their departure, and the property they had got from the Egyptians, it was taken for granted that they had no design to return; and this was in all likelihood the consideration that weighed most with this avaricious king, and determined him to pursue, and either recover the spoil or bring them back, or both. Thus the heart of Pharaoh and his servants was turned against the people, and they said, Why have we let Israel go from serving us? Here was the grand incentive to pursuit; their service was profitable to the state, and they were determined not to give it up.
