denounced by God against the serpent (Ge 3:14), and against Cain (Ge 4:11). These divine maledictions carried their effect with them. Prophetical curses were sometimes pronounced by holy men (Ge 9:25; 49:7; De 27:15; Jos 6:26). Such curses are not the consequence of passion or revenge, they are predictions.
No one on pain of death shall curse father or mother (Ex 21:17), nor the prince of his people (Ex 22:28), nor the deaf (Le 19:14). Cursing God or blaspheming was punishable by death (Le 24:10-16). The words "curse God and die" (R.V., "renounce God and die"), used by Job's wife (Job 2:9), have been variously interpreted. Perhaps they simply mean that as nothing but death was expected, God would by this cursing at once interpose and destroy Job, and so put an end to his sufferings.

CURSE. To curse, signifies to imprecate, to call for mischief upon, or wish evil to, any one. Noah cursed his grandson Canaan, Ge 9:25: Jacob cursed the fury of his two sons, Ge 49:7: Moses enjoins the people of Israel to denounce curses against the violaters of the law, De 27:15-16, &c. Joshua pronounced a curse upon him who should undertake to rebuild Jericho. These curses were such as were either ordained by God himself, and pronounced by men under the influence of his Spirit; or they were predictions of certain evils which would happen to individuals, or to a people, uttered in the form of imprecations. They were not the effects of passion, impatience, or revenge; and, therefore, were not things condemned by God in his law, like the cursing mentioned, Ex 21:17; 22:28; Le 19:14.
