Job 1:5

English Standard Version

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. (Ge 8:20; 1Sa 16:5; Job 2:5; Job 42:8; Ps 10:3) 

New International Version

5 When a period of feasting had run its course, Job would make arrangements for them to be purified. Early in the morning he would sacrifice a burnt offering for each of them, thinking, ‘Perhaps my children have sinned and cursed God in their hearts.’ This was Job’s regular custom. 

New International Reader’s Version

5 The time for enjoying good food would end. Then Job would make plans for his children to be made pure and ‘clean’. He would sacrifice a burnt offering for each of them. He would do it early in the morning. He would think, ‘Perhaps my children have sinned. Maybe they have spoken evil things against God in their hearts.’ That’s what Job always did for his children when he felt they had sinned. 

King James Version

5 And it was so, when the days of their feasting were gone about, that Job sent and sanctified them, and rose up early in the morning, and offered burnt offerings according to the number of them all: for Job said, It may be that my sons have sinned, and cursed God in their hearts. Thus did Job continually.
