Thunder is hardly ever heard in Palestine from 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. 1 Sam. 12:17. Rain in harvest was deemed as extraordinary as snow in summer, Prov. 26:1, and Jerome states that he had never witnessed it in the latter part of June or in July. Comm. on Amos 4:7. In the imaginative philosophy of the Hebrews, thunder was regarded as the voice of Jehovah, Job 37:2, 4–5; 40:9; Ps. 18:13; 29:3–9; Isa. 30:30–31, who dwelt behind the thunder-cloud. Ps. 81:7. Thunder was, to the mind of the Jew, the symbol of divine power, Ps. 29:3, etc., and vengeance. 1 Sam. 2:10; 2 Sam. 22:14.
