We do not need to be as great as Biblical figures of Moses and his father-in-law Raguel to apprehend the connection of people's safety with dispensation of the highest justice. This straight-forward association of top judgement for the benefit of safe decisions is long standing. Josephus, a pharisee of the first century A.D, put it well in his traditional account referring to circa year 1300 B.C.
"But afterward he [Raguel] took him [Moses] to himself: and when he had him alone, he instructed him in what he ought to do; and advised him to leave the trouble of lesser causes to others; but himself to take care of the greater, and of the peoples safety: for that certain others of the Hebrews might be found that were fit to determine causes: but that no body but a Moses could take care of the safety of so many ten thousands." (Antiquities of the Jews — Book III, chapter 4)
