Exodus 10:4-6

New Revised Standard Version, Anglicised Catholic Edition

⁴ For if you refuse to let my people go, tomorrow I will bring locusts into your country. ⁵ They shall cover the surface of the land, so that no one will be able to see the land. They shall devour the last remnant left you after the hail, and they shall devour every tree of yours that grows in the field. ⁶ They shall fill your houses, and the houses of all your officials and of all the Egyptians—something that neither your parents nor your grandparents have seen, from the day they came on earth to this day.”’ Then he turned and went out from Pharaoh.
