(14) I will . . . send all my plagues upon thine heart.--The naturally obdurate heart of Pharaoh, which he had further indurated by his own voluntary action (Exodus 8:15; Exodus 8:32), and which God had begun to harden penally (Exodus 9:12), was now to be softened by a repetition of blow after blow, until it should finally succumb, and yield, and humble itself under the mighty hand of God, and consent to the departure of the whole people, with flocks, and herds, and "little ones."

Verse 14. - I will at this time send all my plagues upon thine heart. A very emphatic announcement. At this time contrasts the immediate future with the past, and tells Pharaoh that the hour of mild warnings and slight plagues is gone by. Now he is to expect something far more terrible God will send all his plagues - every worst form of evil - in rapid succession; and will send them against his heart. Each will strike a blow on that perverse and obdurate heart - each will stir his nature to its inmost depths. Conscience will wake up and insist on being heard. All the numerous brood of selfish fears and alarms will bestir themselves. He will tremble, and be amazed and perplexed. He will forego his pride and humble himself, and beg the Israelites to be gone, and even intreat that, ere they depart, the leaders whom he has so long opposed, will give him their blessing (Exodus 12:32). That thou mayest know. Pharaoh was himself to be convinced that the Lord God of Israel was, at any rate, the greatest of all gods. He was not likely to desert at once and altogether the religion in which he had been brought up, or to regard its gods as nonexistent. But he might be persuaded of one thing - that Jehovah was far above them. And this he practically acknowledges in vers. 27 and 28.

9:13-21 Moses is here ordered to deliver a dreadful message to Pharaoh. Providence ordered it, that Moses should have a man of such a fierce and stubborn spirit as this Pharaoh to deal with; and every thing made it a most signal instance of the power of God has to humble and bring down the proudest of his enemies. When God's justice threatens ruin, his mercy at the same time shows a way of escape from it. God not only distinguished between Egyptians and Israelites, but between some Egyptians and others. If Pharaoh will not yield, and so prevent the judgment itself, yet those that will take warning, may take shelter. Some believed the things which were spoken, and they feared, and housed their servants and cattle, and it was their wisdom. Even among the servants of Pharaoh, some trembled at God's word; and shall not the sons of Israel dread it? But others believed not, and left their cattle in the field. Obstinate unbelief is deaf to the fairest warnings, and the wisest counsels, which leaves the blood of those that perish upon their own heads.For I will at this time send all my plagues upon thine heart,.... Not meaning particularly the plague of the hail, which next follows, so called, because it consisted of various things, as hail, rain, lightning, and thunder, as Aben Ezra, and who observes, that Pharaoh was more terrified with this plague than with any other; but rather all the plagues yet to come, for by them are not meant all the plagues that were in the power of God to inflict, which how many and great they are none can say, but all that he had determined in his mind to bring upon him; and these should not so much affect and afflict his body, as the boils and ulcers had the magicians, but should reach his heart, and fill him with horror and terror:

and upon thy servants, and upon thy people; even all that he intended to bring not only upon himself, but upon his subjects, both high and low:

that thou mayest know, that there is none like unto me in all the earth; for the perfections of his nature, and the works of his hands, particularly his providential dealings with the sons of men, and especially with him.
