Vision of the Israelites of the Manifestation of the Glory of God
Source: Nav
Exodus 24:10, 17
and they saw the God of Israel. Under His feet was a work like a pavement made of sapphire, as clear as the sky itself. / And the sight of the glory of the LORD was like a consuming fire on the mountaintop in the eyes of the Israelites.
Hebrews 12:18–21
For you have not come to a mountain that can be touched and that is burning with fire; to darkness, gloom, and storm; / to a trumpet blast or to a voice that made its hearers beg that no further word be spoken. / For they could not bear what was commanded: “If even an animal touches the mountain, it must be stoned.”
