Definition: Brest in the Bible refers to a place where God's people, Israelites, slept at Mount Sinai during their journey from Egypt. It is believed to be in a cave on top of Mount Sinai or in the middle of a river near Mount Sinai. The precise meaning and historical context are not clear because the book of Exodus does not have any detailed information about the place where God's people were resting at Mount Sinai, only what Moses instructed them to do. This lack of detail has led some scholars to speculate that it may simply be a reference to a cave or river nearby.
