Exodus 24:17Meaning & Commentary from the Church Fathers

The beings most intimately connected to their Creator are the six-winged seraphim, who are filled with love for God. They embody a fiery presence as they serve in His immediate presence, reflecting the truth stated in Hebrews 12:29, which asserts, "for our God is a consuming fire." The seraphim take on this fiery aspect as they behold His majesty, as illustrated by the account: "But the sight of the glory of the Lord on the top of the mountain was before the eyes of the children of Israel as a consuming fire."

The manifestation of the Lord's glory resembles a blazing fire upon the peak of a mountain. This indicates that the cloud in which the Lord disclosed His magnificent presence resembled a storm cloud, constantly illuminated by the brilliant light of lightning (see Ex. 19:16), causing the entire summit of Sinai to burn with fire. This flaming fire signifies a presence analogous to the fire found within a cloud during a severe storm. This extraordinary fire, akin to lightning, appeared continuously before the Israelites, likely throughout the forty days that Moses remained on the mountain.
