12 And the LORD hardened the heart of Pharaoh, and he hearkened not unto them; as the LORD had spoken unto Moses.
13 And the LORD said unto Moses,
14 For I will at this time send all my plagues upon your heart, and upon your servants, and upon your people; that you may know that there is none like me in all the earth.
15 For now I will stretch out my hand, that I may smite you and your people with pestilence; and you shall be cut off from the earth.
16 And indeed for this very cause have I raised you up, to show in you my power; and that my name may be declared throughout all the earth.
17 And yet exalt you yourself against my people, that you will not let them go?
18 Behold, tomorrow about this time I will cause it to rain a very grievous hail, such as has not been in Egypt since the foundation of it even until now.
