Parallel
Numbers 9:20
Brenton's English Septuagint · Berean Standard Bible
And it shall be, whenever the cloud overshadows the tabernacle a number of days, they shall encamp by the word of the Lord, and shall remove by the command of the Lord.
Sometimes the cloud remained over the tabernacle for only a few days, and they would camp at the LORD’s command and set out at the LORD’s command.
