When considering which mountain is the true Biblical Mount Sinai, there are some important criteria to use as a guideline. The Bible and Jewish historians provide information that we can use to narrow down potential candidates.
- The Bible uses the names Sinai and Horeb almost interchangeably. The various viewpoints are that Sinai and Horeb are alternative names for the same mountain; that they are two adjacent mountains, or that Mount Sinai is a peak/mountain within a broader range of mountains or land named Horeb.
- Josephus describes Mount Sinai as the highest peak in the region, specifically near the ancient city of Madyan. It is possible that the entire range was referred to as “Mount Sinai” or “Mount Horeb” in his time.
- Most researchers agree it should be in the ancient land of Midian, where Moses fled after killing an Egyptian who was beating an Israelite slave (Exodus 2, 18). It is debated whether Midian extended into the southern part of today’s Sinai Peninsula in Egypt.
- There must be a cleft somewhere near the top of the mountain. This is the location where Moses saw God and received the Ten Commandments from God (Exodus 33-34).
- There must be a plateau partway up the mountain’s slopes, in which Moses, Aaron, Nadab, Abihu, and the seventy elders could all comfortably fit (Exodus 24).
- There must be a large, open area in which approximately 2-3 million Israelites and their flocks of animals could camp (Exodus 19).
- There must be a noticeable cave at the mountain that the prophet Elijah could have identified and used as a place of shelter (1 Kings 19).
- There must be evidence of water-flow coming down from the mountain, as the Bible describes (Deuteronomy 9).
- Near the last encampment before reaching the mountain, there must be a large open plain where Israelites could have battled the Amalekites (Exodus 17).
- Also near the last encampment, there could be a large rock with a split, matching the story of Moses striking a rock with his staff, resulting in a rush of water pouring forth to quench the thirst of the Israelites. (Exodus 17).
- The mountain should be near the ancient city of Madyan, according to a line of historical sources. The city of Al-Bad in Saudi Arabia is believed to be where Madyan once was.
- There should be evidence of a population communicating in petroglyphs and ancient proto-Hebrew inscriptions.
- There should be evidence of an altar and/or stand where the golden calf was placed and worshipped (Exodus 32).
- There should be evidence of a mass burial where the bodies of the Golden Calf worshippers were placed.
- There could be something resembling an altar below the mountain made of uncut stones, according to specifications given by God to Moses in Exodus 20.
- There could be evidence of 12 pillars near the altar (Exodus 24). It may be organized in three rows of four, as that was the pattern on the Israelite priests’ breastplates.
- There may be evidence of the fiery phenomenon at the top of Mount Sinai as described in the book of Exodus. Researchers disagree on the necessity of this criteria.
At this current point in time, the Doubting Thomas Research Foundation believes that Jabal Maqla (part of the Jabal al-Lawz mountain range in northwestern Saudi Arabia) is the most plausible location for the Biblical Mount Sinai based on the criteria.
