It remained that way continuously: the cloud would cover it, appearing like fire at night.
Numbers 9:16 In-Context
“ ‘A foreigner residing among you is also to celebrate the LORD’s Passover in accordance with its rules and regulations. You must have the same regulations for both the foreigner and the native-born.’ ”
On the day the tabernacle, the tent of the covenant law, was set up, the cloud covered it. From evening till morning the cloud above the tabernacle looked like fire.
That is how it continued to be; the cloud covered it, and at night it looked like fire.
Whenever the cloud lifted from above the tent, the Israelites set out; wherever the cloud settled, the Israelites encamped.
At the LORD’s command the Israelites set out, and at his command they encamped. As long as the cloud stayed over the tabernacle, they remained in camp.
