Exodus 24:12-14

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.” [2 Cor 3:2, 3] So Moses arose with Joshua his attendant, and he went up to the mountain of God. And he said to the elders, “Wait here for us until we come back to you. Remember that Aaron and Hur are with you; whoever has a legal matter, let him go to them.”
