At sa tuwing natatapos ang ikot ng mga araw ng piging, nagpapasugo si Job at ipinatatawag sila; at bumabangon siya nang maaga sa umaga at naghahandog ng mga handog na susunugin ayon sa bilang nilang lahat, sapagkat sinabi ni Job, “Baka nagkasala ang aking mga anak at nilapastangan nila ang Diyos sa kanilang puso.” Ganito ang laging ginagawa ni Job.

They also said (Yerushalmi Yoma 5:7), “A burnt-offering atones for the meditations of the heart that come up in peoples’ souls and the thought of sins.” And likewise is it written (Job 1:5), “When a round of feast days was over, Job would send word to them to sanctify themselves, and, rising early in the morning, he would make burnt-offerings, one for each of them; for Job thought, ‘Perhaps my children have sinned and blasphemed God in their thoughts.’”

This is as the matter of Bava Ben Buta who would bring an Asham Talui (undetermined guilt offering) every day (Keritut 25a). Likewise, Iyov, after his sons' feast, would rise early and bring burnt offerings according to the number of them all. For he told himself: "perhaps my children have sinned [and blasphemed G-d in their hearts]" (Iyov 1:5).
