Job 1:5

1:5 When the days of their feasting were finished, Job would send for them and sanctify them; he would get up early in the morning and offer burnt offerings according to the number of them all. For Job thought, “Perhaps my children have sinned and cursed God in their hearts.” This was Job’s customary practice.

Job 1:11

1:11 But extend your hand and strike everything he has, and he will no doubt curse you to your face!”

Job 1:22

1:22 In all this Job did not sin, nor did he charge God with moral impropriety.

Job 2:5

2:5 But extend your hand and strike his bone and his flesh, and he will no doubt curse you to your face!”

Job 2:9-10

2:9 Then his wife said to him, “Are you still holding firmly to your integrity? Curse God, and die!” 2:10 But he replied, “You’re talking like one of the godless women would do! Should we receive what is good from God, and not also receive what is evil?” In all this Job did not sin by what he said.

Isaiah 8:21

8:21 They will pass through the land destitute and starving. Their hunger will make them angry, and they will curse their king and their God as they look upward.
