Numbers 10:29-33

29One day Moses said to his brother-in-law, Hobab son of Reuel the Midianite, “We are on our way to the place the Lord promised us, for he said, ‘I will give it to you.’ Come with us and we will treat you well, for the Lord has promised wonderful blessings for Israel!”

30But Hobab replied, “No, I will not go. I must return to my own land and family.”

31“Please don’t leave us,” Moses pleaded. “You know the places in the wilderness where we should camp. Come, be our guide.

32If you do, we’ll share with you all the blessings the Lord gives us.”

33They marched for three days after leaving the mountain of the Lord, with the Ark of the Lord’s Covenant moving ahead of them to show them where to stop and rest.
