Exodus 9:16-18

Young's Literal Translation

¹⁶ `And yet for this I have caused thee to stand, so as to show thee My power, and for the sake of declaring My Name in all the earth;

¹⁷ still thou art exalting thyself against My people -- so as not to send them away;

¹⁸ lo, I am raining about [this] time to-morrow hail very grievous, such as hath not been in Egypt, even from the day of its being founded, even until now.
