Numbers 10:36

And it shall be, if thou go with us, yea, it shall be, that what goodness the LORD shall do unto us, the same will we do unto thee.

And they departed from the mount of the LORD three days’ journey: and the ark of the covenant of the LORD went before them in the three days’ journey, to search out a resting place for them.

And the cloud of the LORD was upon them by day, when they went out of the camp.

And it came to pass, when the ark set forward, that Moses said, Rise up, LORD, and let thine enemies be scattered; and let them that hate thee flee before thee.
