Ex 18:21

18:21 look for able men. Delegation is often difficult for an able leader. Men were chosen here on moral rather than intellectual grounds to deal with simple matters. Difficult cases, perhaps those without precedent, were brought to Moses. This is how Israel’s legal system would later function. No difference is made between the sacred and the secular. The entire law was God’s gift, and obedience to it amounted to obedience to God.
