THUNDER @ - is hardly ever heard in Palestine form the middle of April to the middle of September; hence it was selected by Samuel as a striking expression of the divine displeasure toward the Israelites.

Psalms:81:7) Thunder was, to the mind of the Jew, the symbol of divine power Psalms:29:3) etc., and vengeance. ( 1Samuel:2:10; 2 Samuel 22:14)
