Numbers 10:33-36 - The People Set Out
33 So they traveled from the mountain of the LORD, a three-day trip, with the Ark of the Covenant of the LORD traveling in front of them a three day trip to explore a place for them to rest. 34 Moreover, the cloud of the LORD protected them during the day when they left their camp.
35 Whenever the ark was ready to travel, Moses would say: "Arise, LORD, to scatter your enemies, so that whoever hates you will flee from your presence."
36 Whenever the ark was being readied to rest, he would say: "Return, LORD, to the countless thousands of Israel."
