Numbers 9:17-19

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 people 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.
