On the day the Tabernacle was set up, the cloud covered it. But from evening until morning the cloud over the Tabernacle looked like a pillar of fire. This was the regular pattern—at night the cloud that covered the Tabernacle had the appearance of fire. Whenever the cloud lifted from over the sacred tent, the people of Israel would break camp and follow it. And wherever the cloud settled, the peo...ple of Israel would set up camp. In this way, they traveled and camped at the Lord’s command wherever he told them to go. Then they remained in their camp as long as the cloud stayed over the Tabernacle. If the cloud remained over the Tabernacle for a long time, the Israelites stayed and performed their duty to the Lord. Sometimes the cloud would stay over the Tabernacle for only a few days, so the people would stay for only a few days, as the Lord commanded. Then at the Lord’s command they would break camp and move on. Sometimes the cloud stayed only overnight and lifted the next morning. But day or night, when the cloud lifted, the people broke camp and moved on. Whether the cloud stayed above the Tabernacle for two days, a month, or a year, the people of Israel stayed in camp and did not move on. But as soon as it lifted, they broke camp and moved on. So they camped or traveled at the Lord’s command, and they did whatever the Lord told them through Moses.
