Numbers 9:18

"At the commandment of Jehovah the children of Israel journeyed, and at the commandment of Jehovah they encamped: as long as the cloud abode upon the tabernacle, they remained encamped. And when the cloud tarried upon the tabernacle many days, then the children of Israel kept the charge of Jehovah, and journeyed not. And sometimes the cloud was a few days upon the tabernacle; then according to the commandment of Jehovah they remained encamped, and according to the commandment of Jehovah they journeyed. And sometimes the cloud was from evening until morning; and when the cloud was taken up in the morning, they journeyed: or if it continued by day and by night, when the cloud was taken up, they journeyed. Whether it were two days, or a month, or a year, that the cloud tarried upon the tabernacle, abiding thereon, the children of Israel remained encamped, and journeyed not; but when it was taken up, they journeyed. At the commandment of Jehovah they encamped, and at the commandment of Jehovah they journeyed: they kept the charge of Jehovah, at the commandment of Jehovah by Moses."

"At the commandment of Jehovah ..." This phrase occurs no less than seven times in this paragraph, stressing the important truth that God directed and controlled the movements of Israel in the wilderness.

"Two days, or a month, or a year ..." (Numbers 9:22). The word here rendered "year" does not have exactly that meaning. "It indicates a period of time not precisely indicated."[19] The use of "year" in our version (ASV) and in the KJV is a translator's interpretation, "Because the word is literally days of indeterminate number."[20] "Genesis 24:55 shows that this word means a number of days, possibly ten, but usually, it means more than a month."[21] Cook pointed out that it was used idiomatically for a year (Leviticus 25:29), and that "It is an expression equivalent to `a full period,' though not necessarily the period of a year."[22]
