Exodus 10:4-6

Complete Jewish Bible

⁴ Otherwise, if you refuse to let my people go, tomorrow I will bring locusts into your territory. ⁵ One won’t be able to see the ground, so completely will the locusts cover it. They will eat anything you still have that escaped the hail, including every tree you have growing in the field. ⁶ They will fill your houses and those of your servants and of all the Egyptians. It will be like nothing your fathers or their fathers have ever seen since the day they were born until today.’” Then he turned his back and left.
