Exodus 18:12-14

Young's Literal Translation

¹² And Jethro, father-in-law of Moses, taketh a burnt-offering and sacrifices for God; and Aaron cometh in, and all the elders of Israel, to eat bread with the father-in-law of Moses, before God.

¹³ And it cometh to pass on the morrow, that Moses sitteth to judge the people, and the people stand before Moses, from the morning unto the evening;

¹⁴ and the father-in-law of Moses seeth all that he is doing to the people, and saith, `What [is] this thing which thou art doing to the people? wherefore art thou sitting by thyself, and all the people standing by thee from morning till evening?'
