Exodus 24:12-14

Young's Literal Translation

¹² And Jehovah saith unto Moses, `Come up unto Me to the mount, and be there, and I give to thee the tables of stone, and the law, and the command, which I have written to direct them.'

¹³ And Moses riseth -- Joshua his minister also -- and Moses goeth up unto the mount of God;

¹⁴ and unto the elders he hath said, `Abide ye for us in this [place], until that we turn back unto you, and lo, Aaron and Hur [are] with you -- he who hath matters doth come nigh unto them.'
