a mountain in Arabia Petraea, a part of which, or near to which, was Sinai. At Horeb God appeared to Moses in the burning bush, Exodus 3:1 , &c. Hither Elijah retired to avoid the persecution of Jezebel, 1 Kings 19:8 . Sinai and Horeb seem to be two parts of the same mountain; hence the law is sometimes said to be given there.
