Numbers 9:21 Meaning and Commentary

Numbers 9:21

And [so] it was when the cloud abode from even unto the
morning
The whole night, during which time they rested in their beds:

and [that] the cloud was taken up in the morning, then they journeyed;
whether [it was] by day or night that the cloud was taken up, they
journeyed;
whether at morning or midnight; for sometimes, as Aben Ezra observes, they travelled in the night; whensoever their sentinels gave notice that the cloud was taken up, even though at midnight, they arose and prepared for their journey; and by this it is evident, that the appearance by day and night was the same body called the cloud, though beheld in a different view, in the daytime as a cloud, in the nighttime as fire.

Numbers 9:21 In-Context

19 Even when the cloud continued over the tabernacle many days, the people of Israel kept the charge of the LORD, and did not set out.

20 Sometimes the cloud was a few days over the tabernacle, and according to the command of the LORD they remained in camp; then according to the command of the LORD they set out.

21 And sometimes the cloud remained from evening until morning; and when the cloud was taken up in the morning, they set out, or if it continued for a day and a night, when the cloud was taken up they set out.

22 Whether it was two days, or a month, or a longer time, that the cloud continued over the tabernacle, abiding there, the people of Israel remained in camp and did not set out; but when it was taken up they set out.

23 At the command of the LORD they encamped, and at the command of the LORD they set out; they kept the charge of the LORD, at the command of the LORD by Moses.
