Exodus 18:24-26

Young's Literal Translation

²⁴ And Moses hearkeneth to the voice of his father-in-law, and doth all that he said,

²⁵ and Moses chooseth men of ability out of all Israel, and maketh them chiefs over the people, heads of thousands, heads of hundreds, heads of fifties, and heads of tens,

²⁶ and they have judged the people at all times; the hard matter they bring in unto Moses, and every small matter they judge themselves.
