New Defender's Study Bible Notes
1:5 offered burnt offerings. Even though Job was “perfect and upright,” he was careful to offer sacrificial offerings regularly, both for himself and his family, recognizing that their sins, whether willful sins or sins done in ignorance, required sacrifice of innocent substitutes and the shedding of blood as an atonement. This was obviously before the giving of the Mosaic law and establishment of the Levitical offerings, so Job was acting in accord with earlier revelation (Job 23:12). Note also that, in the patriarchal system of the age before Moses, Job was acting as the priestly mediator for his family before the Lord.
