“Yahweh said to Moses, ‘Go to Pharaoh, for I have made his heart and the heart of his servants stubborn so that I can put these signs of Mine in his midst; and so that you may relate in the ears of your son and your son’s son, that I made a mockery of Egypt and My signs that I placed among them – that you may know that I am the Jealous One.’ Moses and Aaron went to Pharaoh and said to him, ‘So said Yahweh, God of the Hebrews: Until when will you refuse to be humbled before Me? Send out My people that they may serve Me! For if you refuse to send forth My people, behold, tomorrow I shall bring a locust-swarm into your border. It will cover the surface of the earth so that one will not be able to see the earth; and it will consume the remaining residue that was left to you by the hail, and it will consume all the trees that grow for you from the field. They will fill your houses, the houses of all your servants, and the houses of all Egypt, such as your fathers and your grandfathers have not seen from the day they came into the earth until this day . . .”
“Yahweh said to Moses, ‘Stretch out your hand over the land of Egypt for the locust-swarm, and it will ascend upon the land of Egypt and eat all the grass of the land, everything that the hail had left.’ Moses stretched his staff over the land of Egypt, and Yahweh guided an east wind through the land all that day and all that night. It became morning and the east-wind carried the locust-swarm. The locust-swarm descended onto the entire land of Egypt and it rested in the entire border of Egypt, very severely; before it there was never a locust-swarm like it and after it there will not be its equal. It covered the surface of the entire land and the land was darkened; it ate all the grass of the land and all the fruit of the tree that the hail had left over. No greenery remained on the trees or the grass of the field in the entire land of Egypt. Pharaoh hastened to summon Moses and Aaron, and he said, ‘I have sinned toward the Jealous One, your God, and to you. And now, please forgive my sin just this time, and entreat the Jealous One, your God, that He remove from me only this death. Moses left Pharaoh and entreated Yahweh. Yahweh turned back a very powerful west wind and it carried the locust-swarm and hurled it toward the Sea of Reeds; not a single locust remained within the entire border of Egypt. But Yahweh hardened the heart of Pharaoh and he did not send out the Children of Israel” (Ex 10:1-20).
