Numbers 10:33-35

And they set forward from the mount of Jehovah three days’ journey; and the ark of the covenant of Jehovah went before them three days’ journey, to seek out a resting-place for them. And the cloud of Jehovah was over them by day, when they set forward from the camp. And it came to pass, when the ark set forward, that Moses said, Rise up, O Jehovah, and let thine enemies be scattered; and let them that hate thee flee before thee.
