Exodus 18:16-18

Young's Literal Translation

¹⁶ when they have a matter, it hath come unto me, and I have judged between a man and his neighbour, and made known the statutes of God, and His laws.'

¹⁷ And the father-in-law of Moses saith unto him, `The thing which thou art doing [is] not good;

¹⁸ thou dost surely wear away, both thou, and this people which [is] with thee, for the thing is too heavy for thee, thou art not able to do it by thyself.
