Exodus 10:2-4

New Century Version

² I also did this so you could tell your children and your grandchildren how I was hard on the Egyptians. Tell them about the miracles I did among them so that all of you will know that I am the Lord.”

³ So Moses and Aaron went to the king and told him, “This is what the Lord, the God of the Hebrews, says: ‘How long will you refuse to be sorry for what you have done? Let my people go to worship me. ⁴ If you refuse to let my people go, tomorrow I will bring locusts into your country.
