Exo 10:2-3 | Clarke | e4.org | Verse 2. That thou mayest tell in the ears of thy son ] That the miracles wrought at this time might be a record for the instruction of the latest posterity, that Jehovah alone, the God of the Hebrews, was the sole Maker, Governor, and Supporter of the heavens and the earth. Thus we find God so did his marvellous works, that they might be had in everlasting remembrance . It was not to crush the poor worm, Pharaoh, that he wrought such mighty wonders, but to convince his enemies, to the end of the world, that no cunning or power can prevail against him; and to show his followers that whosoever trusted in him should never be confounded.

‏ Exodus 10:2-3

Verse 2. That thou mayest tell in the ears of thy son] That the miracles wrought at this time might be a record for the instruction of the latest posterity, that Jehovah alone, the God of the Hebrews, was the sole Maker, Governor, and Supporter of the heavens and the earth. Thus we find God so did his marvellous works, that they might be had in everlasting remembrance. It was not to crush the poor worm, Pharaoh, that he wrought such mighty wonders, but to convince his enemies, to the end of the world, that no cunning or power can prevail against him; and to show his followers that whosoever trusted in him should never be confounded.

Verse 3. How long wilt thou refuse to humble thyself] Had it been impossible for Pharaoh, in all the preceding plagues, to have humbled himself and repented can we suppose that God could have addressed him in such language as the preceding? We may rest assured that there was always a time in which he might have relented, and that it was because he hardened his heart at such times that God is said to harden him, i.e., to give him up to his own stubborn and obstinate heart; in consequence of which he refused to let the people go, so that God had a fresh opportunity to work another miracle, for the very gracious purposes mentioned in Ex 10:2. Had Pharaoh relented before, the same gracious ends would have been accomplished by other means.
