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 And in the cloud prolonging itself over the tabernacle many days, then have the sons of Israel kept the charge of Jehovah, and journey not,
20 and so when the cloud is a number of days over the tabernacle; by the command of Jehovah they encamp, and by the command of Jehovah they journey.
21 And so when the cloud is from evening till morning, when the cloud hath gone up in the morning, then they have journeyed; whether by day or by night, when the cloud hath gone up, then they have journeyed.
22 Whether two days, or a month, or days, in the cloud prolonging itself over the tabernacle, to tabernacle over it, the sons of Israel encamp, and journey not; and in its being lifted up they journey;
23 by the command of Jehovah they encamp, and by the command of Jehovah they journey; the charge of Jehovah they have kept, by the command of Jehovah in the hand of Moses.
