Exodus 9:16-18

New Catholic Bible

¹⁶ Instead, I let you live to show you my power and so that my name might be proclaimed all throughout the earth. ¹⁷ Will you still oppose my people and not let them leave? ¹⁸ Behold, I will send a terribly violent hail tomorrow at this time as has never been seen in Egypt from the day it was founded until today.
