Exodus 10:4-6

Living Bible

^4-5 If you refuse, tomorrow I will cover the entire nation with a thick layer of locusts so that you won’t even be able to see the ground, and they will finish destroying everything that escaped the hail. ⁶ They will fill your palace, and the homes of your officials, and all the houses of Egypt. Never in the history of Egypt has there been a plague like this will be!’” Then Moses stalked out.
