In the wilderness of Mount Sinai, an Angel of the Lord appeared to Moses in a flame of fire within a bush. When Moses drew near to observe this marvel, the voice of the Lord spoke to him, declaring, 'I am the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob.' Moses trembled and dared not look upon God. This same Angel spoke to Moses on Mount Sinai and with the fathers, delivering the living oracles to be given to the people. At the burning bush, the divine Messenger appeared, and God identified Himself as the God of Abraham, Isaac, and Jacob, instructing Moses to tell the Israelites that the Lord God of their fathers had appeared to him, affirming His presence and concern for them. The term "appeared" indicates visibility, suggesting that Moses saw the God of the fathers, who is also identified as the Angel of the Lord.

In Exodus 19:16-20, the awe-inspiring presence of God was revealed at Mount Sinai with thunderings, lightnings, a thick cloud, and the loud sound of a trumpet, causing the people to tremble. Moses brought the people out of the camp to meet with God, standing at the foot of the mountain, which was enveloped in smoke and fire as the Lord descended upon it. The mountain quaked greatly, and as the trumpet blast grew louder, Moses spoke, and God answered him by voice. The Lord called Moses to the top of the mountain, where he went up to receive the Ten Commandments, while the people below quaked in fear at God's proximity. In Exodus 20:18-21, the people witnessed the thunderings, lightning flashes, trumpet sounds, and smoking mountain, trembling and standing afar off. They pleaded with Moses to speak to them instead of God, fearing death if God spoke directly. Moses reassured them not to fear, explaining that God had come to test them so that His fear would be before them to prevent sin. While the people remained at a distance, Moses drew near the thick darkness where God was, showing his unique role in approaching God's presence. In Exodus 33:12-23, Moses conversed with the Lord, seeking assurance of His presence with the people. Moses asked to know God's way and to see His glory, having found grace in His sight. The Lord promised that His Presence would go with them and give them rest, but cautioned that no man could see His face and live. God instructed Moses to stand on a rock, where He would cover him with His hand as His glory passed by, allowing Moses to see only His back. God distinguished between His unapproachable glory and His name and goodness, which Moses could experience as a mortal, revealing that while His full presence was overwhelming, His name offered a relatable connection. In Exodus 34:4-9, Moses ascended Mount Sinai with two newly cut stone tablets, as commanded by the Lord. The Lord descended in a cloud, stood with him, and proclaimed His name, declaring Himself as merciful, gracious, longsuffering, and abounding in goodness and truth, keeping mercy for thousands, forgiving iniquity, transgression, and sin, yet not clearing the guilty. Moses bowed his head, worshiped, and pleaded for the Lord to go among the stiff-necked people, pardon their sins, and take them as His inheritance. This encounter illustrated how a holy God could dwell among a sinful nation through the approachable nature of His name, which encapsulated His character and virtues.
