Exodus 18:21-22

21But do thou provide among all the people able men, such as fear 1God, men of truth, hating covetousness; and place [them] over them, chiefs of thousands, chiefs of hundreds, chiefs of fifties, and chiefs of tens,

22that they may judge the people at all times; and it shall be [that] they shall bring to thee every great matter, and that they shall judge every small matter, and they shall lighten [the task] on thee, and they shall bear [it] with thee.
