Hail.
Particles of ice falling from the clouds. Though hail is usually formed by natural causes not yet perhaps well understood, it is often referred to in scripture as one of the judgements of God. It formed one of the plagues in Egypt. Exodus 9:18-34; Psalms 78:47, Psalms 1:78; Psalms 105:32; and is at times connected with fire or lightning. God smote the Amalekites by 'great stones' from heaven. Joshua 10:11. The hail is called upon to praise Jehovah, because it fulfils His word. Psalms 148:8; Isaiah 28:2, Isaiah 1:28; Haggai 2:17. It will also form a notable part of the judgements of God in His future dealings with this guilty world. Revelation 8:7; Revelation 11:19; Revelation 16:21.
