Contradiction with Numbers 9:22
This verse states that the Israelites remained camped as long as the cloud abode upon the tabernacle, whether it was two days, a month, or a year, contradicting the consistent journeying described in Exodus 40:36 whenever the cloud was taken up.
Numbers 9:22: Or [whether it were] two days, or a month, or a year, that the cloud tarried upon the tabernacle, remaining thereon, the children of Israel abode in their tents, and journeyed not: but when it was taken up, they journeyed.
