Reference: Sinai
Hastings
A holy mountain in the Sinaitic peninsula (whose name is said to be derived from that of Sin, the moon-god). It is called Horeb by Elohist and Deuteronomist, whereas Jahwist and Priestly Narrative employ the name 'Sinai.' Here Moses was granted the vision of the burning bush (Ex 3:1), whereby he first received a call to lead the Israelites to adopt Jahweh as their covenanted God; and here took place the tremendous theophany which is the central event of the Pentateuch, wherein the covenant was ratified.
The identification of Mt. Sinai is a matter of some difficulty, and various attempts to discover it have been made from time to time. The traditional site is Jebel M
