Exodus 10:4-6

Young's Literal Translation

⁴ for if thou art refusing to send My people away, lo, I am bringing in to-morrow the locust into thy border,

⁵ and it hath covered the eye of the land, and none is able to see the land, and it hath eaten the remnant of that which is escaped, which is left to you from the hail, and it hath eaten every tree which is springing for you out of the field;

⁶ and they have filled thy houses, and the houses of all thy servants, and the houses of all the Egyptians, which neither thy fathers nor thy father's fathers have seen, since the day of their being on the ground unto this day,' -- and he turneth and goeth out from Pharaoh.
