Divine Protection under God’s Cloud of Glory

Just as God’s cloud of glory hovered over the Israelites and protected them from Pharaoh’s army and from physical elements at Israel’s exodus out of Egypt (Exodus 13:21–22; 14:19–20), so it will protect God’s righteous people from hostile forces at the end. In that day, they will sing a Song of Salvation: “You were a refuge for the poor, a shelter for the needy in distress, a covert from the downpour and shade from the heat. When the blasts of tyrants beat down like torrents against a wall, or like scorching heat in the desert, you quelled the onslaughts of the heathen. As burning heat by the shade of a cloud, you subdued the power of tyrants” (Isaiah 25:4–5).

“Over the whole site of Mount Zion, and over its solemn assembly, Jehovah will form a cloud by day and a mist glowing with fire by night: above all that is glorious shall be a canopy. It shall be a shelter and shade from the heat of the day, a secret refuge from the downpour and from rain” (Isaiah 4:5–6). While the “day” signifies God’s Day of Judgment, Isaiah’s heatwave and storm imagery typifies the evil powers God lets loose upon a wicked world. The idea of a “canopy,” moreover, denotes a renewal of the marriage covenant between God and his end-time people: “For he who espouses you is your Maker, whose name is Jehovah of Hosts” (Isaiah 54:5).
