Job 1:5; Job 1:11

5 And when the days of the feast had run their course, Job would send and consecrate them, and he would rise early in the morning and offer burnt offerings according to the number of them all. For Job said, "It may be that my children have sinned, and cursed God in their hearts." Thus Job did continually.

11 But stretch out your hand and touch all that he has, and he will curse you to your face."
