Exodus 9:16-21

16However, I have let you stand for this reason: to show you My power, and that My Name might be proclaimed throughout all the earth.

17Yet still you exalt yourself over My people, by not letting them go.

18Behold, tomorrow at about this time, I will cause it to rain a very severe hailstorm, the likes of which has not occurred in Egypt since the day it was founded until now.

19Send word, shelter your cattle and all that you have in the field. For every person and animal found in the field and not brought home, when the hail comes down on them, they will die.’”

20Whoever feared the word of Adonai among the servants of Pharaoh had his own servants and cattle flee into the houses,

21but whoever disregarded the word of Adonai left his servants and cattle in the field.
