A physical manifestation of the presence of God among his people; a special form of theophany particularly associated with Israel being offered guidance on the exodus journey.

To lead Israel

And the LORD went before them in a pillar of cloud to guide their way by day, and in a pillar of fire to give them light by night, so that they could travel by day or night. Neither the pillar of cloud by day nor the pillar of fire by night left its place before the people.

To separate and protect Israel from the armies of Egypt

Exodus 14:19–20 This was just before the crossing of the Red Sea.

And the angel of God, who had gone before the camp of Israel, withdrew and went behind them. The pillar of cloud also moved from before them and stood behind them, so that it came between the camps of Egypt and Israel. The cloud was there in the darkness, but it lit up the night. So all night long neither camp went near the other.

To represent God's presence, especially to Moses

Exodus 33:9 See also Numbers 12:5–6; Deuteronomy 31:15–16; Psalm 99:7

As Moses entered the tent, the pillar of cloud would come down and remain at the entrance, and the LORD would speak with Moses.
