Numbers 9:19

And when the cloud tarried long upon the tabernacle many days, then the children of Israel kept the charge of the Lord, and journeyed not.

Cross-reference

Numbers 9:23 summarizes the same directive — Israel kept the charge by obeying God's command through Moses regarding the cloud.

Exodus 40:37 records the same cloud guidance principle — when cloud remained, they did not journey, reinforcing this pattern.
