In Exodus 32:1-8 the Bible describes how Aaron made a golden calf, and also an altar.
“Now when the people saw that Moses delayed coming down from the mountain, the people gathered together to Aaron, and said to him, “Come, make us gods that shall go before us; for as for this Moses, the man who brought us up out of the land of Egypt, we do not know what has become of him.” And Aaron said to them, “Break off the golden earrings which are in the ears of your wives, your sons, and your daughters, and bring them to me.”
“So all the people broke off the golden earrings which were in their ears, and brought them to Aaron. And he received the gold from their hand, and he fashioned it with an engraving tool, and made a moulded calf. Then they said, “This is your god, O Israel, that brought you out of the land of Egypt!”
So when Aaron saw it, he built an altar before it. And Aaron made a proclamation and said, “Tomorrow is a feast to the LORD.” Then they rose early on the next day, offered burnt offerings, and brought peace offerings; and the people sat down to eat and drink, and rose up to play.
And the LORD said to Moses, “Go, get down! For your people whom you brought out of the land of Egypt have corrupted themselves. “They have turned aside quickly out of the way which I commanded them. They have made themselves a moulded calf, and worshiped it and sacrificed to it, and said, ‘This is your god, O Israel, that brought you out of the land of Egypt!'”
Ron Wyatt discovered this altar with twelve Egyptian style petraglyphs of calves clearly inscribed on it. An archaeologist from Riyadh University became very excited when he saw these calves. He pointed out that they were of Egyptian style, and were not to be found anywhere else in Saudi Arabia.
