Exodus 9:28

9:28 Pray to the Lord, for the mighty ¹  thunderings and hail are too much! ²  I will release you and you will stay no longer.” ³ 

Exodus 9:33

9:33 So Moses left Pharaoh, went out of the city, and spread out his hands to the Lord, and the thunder and the hail ceased, and the rain stopped pouring on the earth.

[9:28]  ¹ sn The text has Heb “the voices of God.” The divine epithet can be used to express the superlative (cf. Jonah 3:3).

[9:28]  ² tn The expression וְרַב מִהְיֹת (vÿrav mihyot, “[the mighty thunder and hail] is much from being”) means essentially “more than enough.” This indicates that the storm was too much, or, as one might say, “It is enough.”

[9:28]  ³ tn The last clause uses a verbal hendiadys: “you will not add to stand,” meaning “you will no longer stay.”
