The complete question is:
In Exodus 3:1 Moses led his flock to the backside of the desert, and came to the mountain of God, even to Horeb. Why is the mountain called the mountain of God?
If the mountain where the transfiguration occured (Matt 17:1-9) could be referred to as “the holy mountain” by Peter (2 Pet 1:17-18), it is not surprising that the mountain where:
- the LORD spoke to Moses in the burning bush
- the LORD met with the people of Israel (Exodus 19:9-20)
- the Law was given
- the Ten Commandments were inscribed by God on the tablets of stone
- the plans for the Tabernacle were given
was called the mountain of God.
