We have here,

I.Instructions given to Moses concerning Israel's motions and encampments, which were so very surprising that if Moses had not express orders about them before they would scarcely have been persuaded to follow the pillar of cloud and fire. That therefore there might be no scruple nor dissatisfaction about it, Moses is told before, 1. Whither they must go, Exo 14:1, Exo 14:2. They had got to the edge of the wilderness (Exo 13:20), and a stage or two more would have brought them to Horeb, the place appointed for their serving God; but, instead of going forward, they are ordered to turn short off, on the right hand from Canaan, and to march towards the Red Sea. Where they were, at Etham, there was no sea in their way to obstruct their passage: but God himself orders them into straits, which might give them an assurance that when his purposes were served he would without fail bring them out of those straits. Note, God sometimes raises difficulties in the way of the salvation of his people, that he may have the glory of subduing them, and helping his people over them. 2. What God designed in these strange orders. Moses would have yielded an implicit obedience, though God had given him no reason; but shall he hide from Moses the thing that he does? No, Moses shall know, (1.) That Pharaoh has a design to ruin Israel, Exo 14:3. (2.) That therefore God has a design to ruin Pharaoh, and he takes this way to effect it, Exo 14:4. Pharaoh's sagacity would conclude that Israel was entangled in the wilderness and so would become an easy prey to him; and, that he might be the more apt to think so, God orders them into yet greater entanglements; also, by turning them so much out of their road, he amazes him yet more, and gives him further occasion to suppose that they were in a state of embarrassment and danger. And thus (says God) I will be honoured upon Pharaoh. Note, [1.] All men being made for the honour of their Maker, those whom he is not honoured by he will be honoured upon. [2.] What seems to tend to the church's ruin is often overruled to the ruin of the church's enemies, whose pride and malice are fed by Providence, that they may be ripened for destruction.

II.Pharaoh's pursuit of Israel, in which, while he gratifies his own malice and revenge, he is furthering the accomplishment of God's counsels concerning him. It was told him that the people fled, Exo 14:5. Such a fright was he in, when he gave them leave to go, that when the fright was a little over he either forgot, or would not own, that they departed with his consent, and therefore was willing that it should be represented to him as a revolt from their allegiance. Thus what may easily be justified is easily condemned, by putting false colours upon it. Now, hereupon,

1.He reflects upon it with regret that he had connived at their departure. He and his servants, though it was with the greatest reason in the world that they had let Israel go, yet were now angry with themselves for it: Why have we done thus? (1.) It vexed them that Israel had their liberty, that they had lost the profit of their labours, and the pleasure of chastising them. It is meat and drink to proud persecutors to trample upon the saints of the Most High, and say to their souls, Bow down, that we may go over; and therefore it vexes them to have their hands tied. Note, The liberty of God's people is a heavy grievance to their enemies, Est 5:12, Est 5:13; Act 5:17, Act 5:33. (2.) It aggravated the vexation that they themselves had consented to it, thinking now that they might have hindered it, and that they needed not to have yielded, though they had stood it out to the last extremity. Thus God makes men's envy and rage against his people a torment to themselves, Psa 112:10. It was well done to let Israel go, and what they would have reflected on with comfort if they had done it from an honest principle; but doing it by constraint, they called themselves a thousand fools for doing it, and passionately wished it undone again. Note, It is very common, but very absurd and criminal, for people to repent of their good deeds; their justice and charity, and even their repentance, are repented of. See an instance somewhat like this, Jer 34:10, Jer 34:11.

2.He resolves, if possible, either to reduce them or to be revenged on them; in order to this, he levies an army, musters all his force of chariots and horsemen, Exo 14:17, Exo 14:18 (for, it should seem, he took no foot with him, because the king's business required haste), and thus he doubts not but he shall re-enslave them, Exo 14:6, Exo 14:7. It is easy to imagine what a rage Pharaoh was now in, roaring like a lion disappointed of his prey, how his proud heart aggravated the affront, swelled with indignation, scorned to be baffled, longed to be revenged: and now all the plagues are as if they had never been. He has quite forgotten the sorrowful funerals of his firstborn, and can think of nothing but making Israel feel his resentments; now he thinks he can be too hard for God himself; for, otherwise, could he have hoped to conquer a people so dear to him? God gave him up to these passions of his own heart, and so hardened it. It is said (Exo 14:8), The children of Israel went out with a high hand, that is, with a great deal of courage and bravery, triumphing in their release, and resolved to break through the difficulties that lay in their way. But the Egyptians (Exo 14:9) pursued after them. Note, Those that in good earnest set their faces heaven-ward, 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, nor go out without raging, Mar 9:26.

I will harden Pharaoh's heart - After relenting and giving them permission to depart, he now changes his mind and determines to prevent them; and without any farther restraining grace, God permits him to rush on to his final ruin, for the cup of his iniquity was now full.

And I will harden Pharaoh's heart,.... Once more, as he had often done:

that he shall follow after them: to Pihahiroth, and even into the sea after them:

and I will be honoured upon Pharaoh, and upon all his host; in his wisdom, faithfulness, power, and justice, by the destruction of them:

that the Egyptians may know that I am the Lord; the only Jehovah, the Lord God omnipotent; even those that feel the weight of his hand while troubling their host, and bringing the waters upon them; especially those that shall remain in the land, and will not be involved in the catastrophe:

and they did so: the Israelites turned to the right to Pihahiroth, instead of going by Bishbesh and Tinah (Bubastis and Pelusium), and so along the sea coast towards Gaza and Ascalon, and encamped there between Migdol and the sea over against Baalzephon, as they were ordered and directed.

the wilderness hath shut them in--Pharaoh, who would eagerly watch their movements, was now satisfied that they were meditating flight, and he naturally thought from the error into which they appeared to have fallen by entering that defile, he could intercept them. He believed them now entirely in his power, the mountain chain being on one side, the sea on the other, so that, if he pursued them in the rear, escape seemed impossible.
