- Sinai – the specific peak, name mostly used in Exodus and Numbers
- Horeb – used more broadly for the mountain region where Sinai is located, especially in Deuteronomy when Moses retells the story
Mount Sinai is the mountain where Moses received the Law and the Ten Commandments from God (Exodus 19-20). The mountain is sometimes called Horeb in Scripture, and the two names generally refer to the same mountain or the surrounding mountain region.
