Mount Horeb is the mountain at which the Ten Commandments were given to Moses by Yahweh, according to the Book of Deuteronomy in the Hebrew Bible. It is described in two places (the Book of Exodus and the Books of Kings) as הַר הָאֱלֹהִים the “Mountain of Elohim”. The mountain is also called the Mountain of YHWH.
In other biblical passages, these events are described as having transpired at Mount Sinai. Although most scholars consider Sinai and Horeb to have been different names for the same place, there is a minority body of opinion that they may have been different locations.
The Protestant reformer John Calvin took the view that Sinai and Horeb were the same mountain, with the eastern side of the mountain being called Sinai and the western side being called Horeb. Abraham Ibn Ezra suggested that there was one mountain, “only it had two tops, which bore these different names.” Locally, around Saint Catherine’s Monastery, which is built adjacent to Mount Sinai and to Willow Peak, the latter is considered to be the Biblical Mount Horeb.
