Mission Statement

The Doubting Thomas Research Foundation is dedicated to documenting the true location of Biblical Mt. Sinai. Among the many sites proposed, we believe that Jabal Maqla in Saudi Arabia is the best candidate for where the Israelites traveled after fleeing slavery in Egypt.

As we continue to study this subject, we remain firmly dedicated to intellectual honesty and integrity, and if new information arises that suggests another location, we will follow the evidence until it leads us to the truth, wherever that may be.


The Doubting Thomas Research Foundation is a 501(c)(3) non-profit dedicated to investigating the historicity of Biblical accounts, including documenting the theories about the location of Mount Sinai, and researching possible reconciliations of the Biblical account with modern understandings of history and science. It is not a proselytizing organization.

Our Goal

We seek for the truth wherever it may lead. We are committed to the highest standards of integrity and academic honesty, and will review our research when new evidence is brought to light regarding competing theories.


We will, at all times, conduct ourselves with the highest standards of professionalism, and will never seek to disparage opposing viewpoints or those that hold opposing viewpoints.


As a 501(c)(3) non-profit organization, we will always be open and transparent with our donors about how our foundation operates. Donors can reach out to us at any point and request information about our operations and how their dollars are being used.

Research Sourcing

We base our research on a wide variety of sources, including primary documents, religious texts and traditions, modern scholarly assessment, and on-the-ground visitation. We will consider valid and relevant evidence from any of these types of sources during the course of our studies.
