INTRODUCTION TO EXODUS 10 This chapter is introduced with giving the reasons why the Lord hardened the heart of Pharaoh, Exo 10:1. Moses and Aaron go in to him, and once more demanded in the name of the Lord the dismission of the people of Israel, and in case of refusal, threatened him with locusts being sent into his country, which should make terrible havoc in all his coasts, Exo 10:3, the servants of Pharaoh entreat him to let them go, upon which Moses and Aaron are brought in again, and treated with about the terms of their departure; but they, insisting upon taking all with them, men, women, and children, and flocks and herds, and Pharaoh not willing that any but men should go, they are drove from his presence in wrath, Exo 10:7 wherefore the locusts were brought on all the land, which made sad devastation in it, Exo 10:12, and this wrought on Pharaoh so far as to acknowledge his sin, pray for forgiveness, and to desire Moses and Aaron to entreat the Lord to remove the plague, which they did, and it was removed accordingly, but still Pharaoh's heart was hardened, Exo 10:16 then followed the plague of thick darkness over all the land for three days, which brought Pharaoh to yield that all should go with them excepting their flocks and herds; but Moses not only insisted that not a hoof should be left behind, but that Pharaoh should give them sacrifices and burnt offerings, Exo 10:21. Pharaoh's heart was hardened, and he refused to comply, and Moses was bid to be gone, and take care never to see his face any more, and which Moses agreed to, Exo 10:27.
