Exodus 10:5-7

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.

⁷ The court officials now came to Pharaoh and asked him, “Are you going to destroy us completely? Don’t you know even yet that all Egypt lies in ruins? Let the men go and serve Jehovah their God!”
