The people fled - This was a natural inference from the change of direction, which indicated a determination to escape from Egypt. Up to the time when that information reached Pharaoh both he and his people understood that the Israelites would return after keeping a festival in the district adjoining Etham. From Etham the intelligence would be forwarded by the commander of the garrison to Rameses in less than a day, and the cavalry, a highly-disciplined force, would be ready for immediate departure.

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.

And it was told the king of Egypt,.... By some of the Egyptians, or mixed multitude that went out with Israel, but returned upon their encampment at the Red sea, or by some spies Pharaoh sent with them to observe their motions: the Targums of Jonathan and Jarchi make use of a word which Buxtorf translates military officers: and the latter says, they went out with them the three days' journey, but the Israelites not returning to Egypt (as expected), they tell Pharaoh of it the fourth day; and on the fifth and sixth he pursued them, and in the night of the seventh went into the sea after them, and on the morning they (the Israelites) sung the song, which was the seventh of the passover: these reported to Pharaoh:

that the people fled; that under a pretence of going three days' journey into the wilderness, to serve and sacrifice to the Lord, they were about to make their escape out of the land:

and the heart of Pharaoh and of his servants were turned against the people; who had so much favour in their sight, not only to give them leave to go, and to hasten their departure, but to lend and give them things of great value; but now their hearts were filled with hatred of them, and with malice and revenge:

and they said, why have we done this, that we have let Israel go from serving us? not Pharaoh only, but his servants said so, even those who had entreated him to let them go, Exodus 10:7 yet now repent of it, and cannot think what reason they had to do it, when at that time they saw reason, and gave a very sufficient one, namely, the destruction of Egypt; but now the judgments and plagues of God being no more upon them, they recollect the great service of the Israelites to them and the benefits and advantages they had reaped by it, and the loss they had sustained by parting with them, and therefore reflect upon themselves for such a piece of conduct.

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?

14:5 And it was told the king that the people fled - He either forgot, or would not own that they had departed with his consent; and therefore was willing it should be represented to him as a revolt from their allegiance.

5. the heart of Pharaoh and of his servants was turned against the people, &c.-Alas, how soon the obduracy of this reprobate king reappears! He had been convinced, but not converted-overawed, but not sanctified by the appalling judgments of heaven. He bitterly repented of what he now thought a hasty concession. Pride and revenge, the honor of his kingdom, and the interests of his subjects, all prompted him to recall his permission to reclaim those runaway slaves and force them to their wonted labor. Strange that he should yet allow such considerations to obliterate or outweigh all his painful experience of the danger of oppressing that people. But those whom the Lord has doomed to destruction are first infatuated by sin.

14:1-9 Pharaoh would think that all Israel was entangled in the wilderness, and so would become an easy prey. But God says, I will be honoured upon Pharaoh. All men being made for the honour of their Maker, those whom he is not honoured by, he will be honoured upon. What seems to tend to the church's ruin, is often overruled to the ruin of the church's enemies. While Pharaoh gratified his malice and revenge, he furthered the bringing to pass God's counsels concerning him. Though with the greatest reason he had let Israel go, yet now he was angry with himself for it. God makes the envy and rage of men against his people, a torment to themselves. Those who set their faces heavenward, and will live godly in Christ Jesus, must expect to be set upon by Satan's temptations and terrors. He will not tamely part with any out of his service.
