Frozen rain-drops; one of the plagues of Egypt (Ex. 9:23). It is mentioned by Haggai as a divine judgment (Hag. 2:17). A hail-storm destroyed the army of the Amorites when they fought against Joshua (Josh. 10:11). Ezekiel represents the wall daubed with untempered mortar as destroyed by great hail-stones (Ezek. 13:11). (See also 38:22; Rev. 8:7; 11:19; 16:21.)
