Sinai means in the bible: Three months after the Exodus, the Israelites reached a mountain. The exact location of the mountain is disputed. Some scholars believe it to have been in Edom. It was probably located in the south of the peninsula, between Aqabah and Suez. This is where it can be identified with Jebel Musa. This was an ancient sanctuary that belonged to Sin the Babylonian moongod. The tabernacle and Ten Commandments were presented to Israel here by God via Moses. The people created a golden calf for worship while Moses was on the mountain with God. It lasted for a little more than one year Num. 1:1.
