Exodus Chapter 24 KJV
1Moses is called up into the mountain. 3The people promise obedience. 4Moses buildeth an altar and twelve pillars; and sprinkleth the blood of the covenant. 9The glory of God appeareth to Moses, Aaron, and the elders of Israel. 12Moses being called up into the mount leaveth Aaron and Hur in charge of the people. 15Moses goeth into the mount, and continueth there forty days and forty nights.
