On the third day after Israel's arrival at Mount Sinai, God prepares to descend upon the mountain to meet with His people and establish His covenant with them. Moses has already conveyed God's initial proposal to the Israelites, and they have agreed to obey His voice and keep His covenant. The people have spent two days consecrating themselves, washing their clothes, and abstaining from physical intimacy as Moses instructed, preparing for this momentous encounter. God has warned Moses to set boundaries around the mountain, forbidding anyone from touching it under penalty of death, as the Lord will descend upon Sinai in the sight of all the people.
[16] Then it came to pass on the third day, in the morning, that there were thunderings and lightnings, and a thick cloud on the mountain; and the sound of the trumpet was very loud, so that all the people who were in the camp trembled. [17] And Moses brought the people out of the camp to meet with God, and they stood at the foot of the mountain. [18] Now Mount Sinai was completely in smoke, because the Lord descended upon it in fire. Its smoke ascended like the smoke of a furnace, and the whole mountain quaked greatly. [19] And when the blast of the trumpet sounded long and became louder and louder, Moses spoke, and God answered him by voice. [20] Then the Lord came down upon Mount Sinai, on the top of the mountain. And the Lord called Moses to the top of the mountain, and Moses went up.
The prophet Elijah flees to Mount Horeb after Queen Jezebel threatens his life for executing the prophets of Baal following his dramatic victory on Mount Carmel. Exhausted and despondent, Elijah travels forty days through the wilderness, sustained by food provided by an angel. Upon reaching the mountain, he takes shelter in a cave where the Lord questions why he has come. Elijah responds that he has been zealous for the Lord, but the Israelites have abandoned the covenant, destroyed the altars, and killed the prophets, leaving him alone and hunted. The Lord then instructs Elijah to stand on the mountain to witness His presence passing by.
[11] Then He said, “Go out, and stand on the mountain before the Lord.” And behold, the Lord passed by, and a great and strong wind tore into the mountains and broke the rocks in pieces before the Lord, but the Lord was not in the wind; and after the wind an earthquake, but the Lord was not in the earthquake; [12] and after the earthquake a fire, but the Lord was not in the fire; and after the fire a still small voice.
[13] So it was, when Elijah heard it, that he wrapped his face in his mantle and went out and stood in the entrance of the cave. Suddenly a voice came to him, and said, “What are you doing here, Elijah?”
[14] And he said, “I have been very zealous for the Lord God of hosts; because the children of Israel have forsaken Your covenant, torn down Your altars, and killed Your prophets with the sword. I alone am left; and they seek to take my life.”
[15] Then the Lord said to him: “Go, return on your way to the Wilderness of Damascus; and when you arrive, anoint Hazael as king over Syria. [16] Also you shall anoint Jehu the son of Nimshi as king over Israel. And Elisha the son of Shaphat of Abel Meholah you shall anoint as prophet in your place.
The author has been urging Hebrew Christians to persevere in faith despite persecution and hardship, warning them against falling away from God's grace. He has just encouraged them to pursue holiness and peace, citing Esau as an example of someone who despised his birthright and found no opportunity for repentance. The author reminded them that they have access to God through Christ's mediation and should not refuse His voice, as their spiritual privileges far exceed those of ancient Israel. He emphasized running the race with endurance, fixing their eyes on Jesus who endured the cross, and accepting God's discipline as evidence of their sonship rather than viewing hardships as punishment.
[18] For you have not come to the mountain that may be touched and that burned with fire, and to blackness and darkness and tempest, [19] and the sound of a trumpet and the voice of words, so that those who heard it begged that the word should not be spoken to them anymore. [20] (For they could not endure what was commanded: “And if so much as a beast touches the mountain, it shall be stoned or shot with an arrow.” [21] And so terrifying was the sight that Moses said, “I am exceedingly afraid and trembling.”)
[22] But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, to an innumerable company of angels, [23] to the general assembly and church of the firstborn who are registered in heaven, to God the Judge of all, to the spirits of just men made perfect, [24] to Jesus the Mediator of the new covenant, and to the blood of sprinkling that speaks better things than that of Abel.
[25] See that you do not refuse Him who speaks. For if they did not escape who refused Him who spoke on earth, much more shall we not escape if we turn away from Him who speaks from heaven, [26] whose voice then shook the earth; but now He has promised, saying, “Yet once more I shake not only the earth, but also heaven.” [27] Now this, “Yet once more,” indicates the removal of those things that are being shaken, as of things that are made, that the things which cannot be shaken may remain.
Jesus has just taught his disciples about the cost of following him, emphasizing self-denial and the willingness to lose one's life for his sake. He warned that some standing with him would not taste death before seeing the kingdom of God. About eight days after these teachings, Jesus takes Peter, John, and James up a mountain to pray. While praying, Jesus's appearance transforms dramatically—his face changes and his clothes become dazzling white. Moses and Elijah appear in glory beside him, discussing his upcoming departure that he will accomplish in Jerusalem. Peter, along with John and James, struggles to stay awake but witnesses this glorious scene. As Moses and Elijah prepare to leave, Peter suggests building three shelters for them. While Peter speaks, a cloud overshadows them, and a voice from the cloud declares Jesus as God's chosen Son, commanding them to listen to him.
[27] But I tell you truly, there are some standing here who shall not taste death till they see the kingdom of God.”
[28] Now it came to pass, about eight days after these sayings, that He took Peter, John, and James and went up on the mountain to pray. [29] As He prayed, the appearance of His face was altered, and His robe became white and glistening. [30] And behold, two men talked with Him, who were Moses and Elijah, [31] who appeared in glory and spoke of His decease which He was about to accomplish at Jerusalem. [32] But Peter and those with him were heavy with sleep; and when they were fully awake, they saw His glory and the two men who stood with Him. [33] Then it happened, as they were parting from Him, that Peter said to Jesus, “Master, it is good for us to be here; and let us make three tabernacles: one for You, one for Moses, and one for Elijah”—not knowing what he said.
[34] While he was saying this, a cloud came and overshadowed them; and they were fearful as they entered the cloud. [35] And a voice came out of the cloud, saying, “This is My beloved Son. Hear Him!” [36] When the voice had ceased, Jesus was found alone. But they kept quiet, and told no one in those days any of the things they had seen.
