New Defender's Study Bible Notes
26:5 my laws. Long before Moses, there were divine commandments and laws, and Abraham obeyed them. Certain law codes found among the Babylonians, the Hittites and others also antedate Moses and agree in many respects with the Mosaic laws, perhaps reflecting a primeval system given by God (possibly only verbally) that disappeared after Babel except for those, like Abraham, who retained and obeyed the truth. Note also the same implication in Job 23:12.
