Now the Lord was going before them by day in a pillar of cloud to lead them in the way, and by night in a pillar of fire to give them light, so that they could travel day or night.
The angel of God, who was going before the camp of Israel, moved and went behind them, and the pillar of cloud moved from before them and stood behind them.
Whether it was for two days, or a month, or a year, that the cloud prolonged its stay over the tabernacle, the Israelites remained camped without traveling; but when it was taken up, they traveled on.
