Numbers 10:33-36

So they set out from the mount of the LORD three days’ journey. And the ark of the covenant of the LORD went before them three days’ journey, to seek out a resting place for them. And the cloud of the LORD was over them by day, whenever they set out from the camp. And whenever the ark set out, Moses said, “Arise, O LORD, and let your enemies be scattered, and let those who hate you flee before you.” And when it rested, he said, “Return, O LORD, to the ten thousand thousands of Israel.”
