Answer
Mount Horeb in the Bible is another name for Mount Sinai, the mountain where the Hebrew people entered into a covenant with God after escaping from bondage in Egypt (Deuteronomy 5:2; 1 Kings 8:9; 2 Chronicles 5:10). Mount Horeb is also the place where Moses received the Ten Commandments and the laws, rules, and instructions for the people before continuing on their journey through the desert toward the Promised Land (Exodus 33:6; Malachi 4:4). “The mountain of God” is another name in the Bible for Mount Horeb or Mount Sinai (Exodus 3:1; Exodus 4:27; Exodus 18:5).
Horeb comes from a Hebrew term meaning “desert.” Most of the events that the book of Exodus describes as happening at Mount Sinai are located at Mount Horeb in the book of Deuteronomy. Deuteronomy uses the name Horeb exclusively for the mountain of God except in one verse, Deuteronomy 33:2. However, this mention of Sinai could refer to the wilderness of Sinai rather than the mountain.
Before the exodus, while Moses was tending the flocks of his father-in-law, Jethro, he came one day to the slopes of Mount Horeb. There he caught sight of a bush that was on fire but not burning up. As Moses investigated the phenomenon, God spoke to him from the flames. Calling him by name, the Lord told Moses to go to Pharaoh and deliver the people of Israel out of slavery in Egypt (Exodus 3:1-12).
After the exodus, as the people wandered in the desert, they suffered from thirst and began to complain to Moses about having no water. The Lord commanded Moses to strike the rock.At Horeb, to acquire water for drinking (Exodus 17:1-7).
In Exodus 19—20, the Israelites camped at the base of Mount Horeb while Moses ascended the mountain to receive instructions from God. They were informed that from the mountain, they would receive God’s commandments and hear His voice. After three days of preparation, God would descend in full view of all the people. Moses established boundaries on their movement, and they were strictly forbidden, under the threat of death, from even touching the mountain. On the third day, amidst thunder, lightning, and trumpet sounds, a dense cloud of smoke enveloped the mountain as God descended upon it. Subsequently, Moses brought down the Ten Commandments and all the laws.
The book of Deuteronomy reaffirms that on Mount Horeb, God established a covenant with the Israelites “The LORD our God made a covenant with us in Horeb.”, (Deuteronomy 5:2) and delivered the Ten Commandments (Deuteronomy 5:6-21). Additionally, while encamped at Mount Horeb, the people crafted a golden calf idol for worship, which triggered God’s anger (Deuteronomy 9:13-29;Psalm 106:19).
From Mount Horeb, the Israelites journeyed towards Kadesh-barnea, an eleven-day trek “(There are eleven days’ journey from Horeb by the way of mount Seir unto Kadesh-barnea.)”, (Deuteronomy 1:2,19) “And when we departed from Horeb, we went through all that great and terrible wilderness, which ye saw by the way of the mountain of the Amorites, as the LORD our God commanded us; and we came to Kadesh-barnea.”, (Deuteronomy 1:2,19), it is recorded that the prophet Elijah later sought refuge on Mount Horeb due to Jezebel’s anger (1 Kings 19:1-8). While there, he resided in a cave and experienced a remarkable encounter with God, who communicated with him not through the windstorm, earthquake, or fire, but in a gentle whisper. At Horeb, God also directed Elijah to anoint Hazael as the king of Syria and Jehu as the king of Israel, and He appointed Elisha as the prophet to follow Elijah (1 Kings 19:9-21).
