So there was hail— Universal hail, Exodus 9:25 demonstrative of its supernatural origin, as hail is generally partial; more supernatural, as general in all parts of Egypt, except that where the children of Israel made their abode, see Exodus 9:26.; and still more supernatural, as mingled with fire: the Hebrew is emphatical; fire catching itself among the hail; i.e. says Ainsworth, one flash of lightning taking hold of another; and so, the flames enfolding themselves, increased and burned more terribly. The word is used only here and Ezekiel 1:4.
