Locusts (Exodus 10:12 - Exodus 10:20)
And the LORD said unto Moses, Stretch out thine hand over the land of Egypt for the locusts, that they may come up upon the land of Egypt, and eat every herb of the land, even all that the hail hath left.
And Moses stretched forth his rod over the land of Egypt, and the LORD brought an east wind upon the land all that day, and all that night; and when it was morning, the east wind brought the locusts.
And the locusts went up over all the land of Egypt, and rested in all the coasts of Egypt: very grievous were they; before them there were no such locusts as they, neither after them shall be such.
For they covered the face of the whole earth, so that the land was darkened; and they did eat every herb of the land, and all the fruit of the trees which the hail had left: and there remained not any green thing in the trees, or in the herbs of the field, through all the land of Egypt.
Then Pharaoh called for Moses and Aaron in haste; and he said, I have sinned against the LORD your God, and against you.
Now therefore forgive, I pray thee, my sin only this once, and intreat the LORD your God, that he may take away from me this death only.
And he went out from Pharaoh, and intreated the LORD.
And the LORD turned a mighty strong west wind, which took away the locusts, and cast them into the Red sea; there remained not one locust in all the coasts of Egypt.
But the LORD hardened Pharaoh's heart, so that he would not let the children of Israel go.
Darkness (Exodus 10:21 - Exodus 10:28)
And the LORD said unto Moses, Stretch out thine hand toward heaven, that there may be darkness over the land of Egypt, even darkness which may be felt.
And Moses stretched forth his hand toward heaven; and there was a thick darkness in all the land of Egypt three days:
They saw not one another, neither rose any from his place for three days: but all the children of Israel had light in their dwellings.
And Pharaoh called unto Moses, and said, Go ye, serve the LORD; only let your flocks and your herds be stayed: let your little ones also go with you.
And Moses said, Thou must give us also sacrifices and burnt offerings, that we may sacrifice unto the LORD our God.
Our cattle also shall go with us; there shall not an hoof be left behind; for thereof must we take to serve the LORD our God; and we know not with what we must serve the LORD, until we come thither.
But the LORD hardened Pharaoh's heart, and he would not let them go.
And Pharaoh said unto him, Get thee from me, take heed to thyself, see my face no more; for in that day thou seest my face thou shalt die.
And Moses said, Thou hast spoken well, I will see thy face again no more.
And the LORD said unto Moses, Yet will I bring one plague more upon Pharaoh, and upon Egypt; afterwards he will let you go hence: when he shall let you go, he shall surely thrust you out hence altogether.
Speak now in the ears of the people, and let every man borrow of his neighbour, and every woman of her neighbour, jewels of silver, and jewels of gold.
