Exodus 9:13-16

13Then the Lord said to Moses, “Get up early in the morning and stand before Pharaoh. Tell him, ‘This is what the Lord, the God of the Hebrews, says: Let my people go, so they can worship me.

14If you don’t, I will send more plagues on you and your officials and your people. Then you will know that there is no one like me in all the earth.

15By now I could have lifted my hand and struck you and your people with a plague to wipe you off the face of the earth.

16But I have spared you for a purpose—to show you my power and to spread my fame throughout the earth.
