Numbers 10:29-36

Then Moses said to Hobab the son of Reuel the Midianite, Moses’ father-in-law, “We are setting out to the place of which the LORD said, ‘I will give it to you’; come with us and we will do you good, for the LORD has promised good concerning Israel.” But he said to him, “I will not come, but rather will go to my own land and relatives.” Then he said, “Please do not leave us, inasmuch as you know where we should camp in the wilderness, and you will be as eyes for us. So it will be, if you go with us, that whatever good the LORD does for us, we will do for you.” Thus they set out from the mount of the LORD three days’ journey, with the ark of the covenant of the LORD journeying in front of them for the three days, to seek out a resting place for them. The cloud of the LORD was over them by day when they set out from the camp. Then it came about when the ark set out that Moses said, “Rise up, O LORD! And let Your enemies be scattered, And let those who hate You flee before You.” When it came to rest, he said, “Return, O LORD, To the myriad thousands of Israel.”
