Exodus 24:12-16

Now the Lord said to Moses, “Come up to Me on the mountain and stay there, and I will give you the stone tablets with the Law and the commandments which I have written for their instruction.”

So Moses got up along with Joshua his servant, and Moses went up to the mountain of God.

But to the elders he said, “Wait here for us until we return to you. And behold, Aaron and Hur are with you; whoever has a legal matter, have him approach them.”

Then Moses went up to the mountain, and the cloud covered the mountain.

The glory of the Lord settled on Mount Sinai, and the cloud covered it for six days; and on the seventh day He called to Moses from the midst of the cloud.
