John Wesley on 2 Chronicles 19:8

The fathers - Persons of other tribes eminent for their dignity, ability and integrity. But whether these persons made up one court, called the Sanhedrim, by which all causes ecclesiastical and civil were decided; or there were two distinct courts, the one ecclesiastical, consisting of the priests and Levites; the other civil, consisting of the chief of the fathers of Israel, it is not easy to determine. The Lord - For matters concerning the laws and worship, of God. Controversies - For matters of difference between man and man. When - When Jehoshaphat and his company were returned to Jerusalem, he made this order concerning establishing judges there.
