Hailstones
Wilson's Dictionary of Bible Types [1]
Psalm 18:12-13 (a) This type represents the words of our Lord. By this poetic language the Psalmist is describing the power and fierce anger of GOD in judgment. The words of GOD are compared to many things in the Scriptures; sometimes they are for blessing, and sometimes for condemnation.
Ezekiel 13:11 (a) The type is used in this passage to reveal the power of GOD by which He will smash and destroy the works of His enemies. (See Ezekiel 38:22).
American Tract Society Bible Dictionary [2]
Drops of rain formed into ice by the power of cold in the upper regions of the atmosphere. Hail was among the plagues of Egypt, Exodus 9:24 , and was the more terrible, because it rarely occurred in that country. Hail was also made use of by God for defeating an army of Canaanites, Joshua 10:11; and is used figuratively to represent terrible judgments, Isaiah 28:2; Revelation 16:21 .
