Numbers 9

Numbers 9:15

And on the day that the tabernacle was reared up the cloud covered the tabernacle, namely, the tent of the testimony: and at even there was upon the tabernacle as it were an appearance of fire, until the morning.

In the day, that the tabernacle was perfectly set up, God gave visible testimony of his presence therein; appearing, in the day time, as a cloud in the Holy of Holies, over the ark; and, in the night time, as a lightsome fire over the same.

Numbers 9:18

At the commandment of the LORD the children of Israel journeyed.

Upon the will of God, signified really to them by the stay or removal of the cloud, they disposed of their journey or abode.
