Exodus 9:15-19

For now I will stretch out my hand, that I may smite thee and thy people with pestilence; and thou shalt be cut off from the earth.

And in very deed for this cause have I raised thee up, for to shew in thee my power; and that my name may be declared throughout all the earth.

As yet exaltest thou thyself against my people, that thou wilt not let them go?

Behold, to morrow about this time I will cause it to rain a very grievous hail, such as hath not been in Egypt since the foundation thereof even until now.

Send therefore now, and gather thy cattle, and all that thou hast in the field; for upon every man and beast which shall be found in the field, and shall not be brought home, the hail shall come down upon them, and they shall die.
