Numbers 10:29-33

29Moses spoke to Reuel's son, Hobab. He was the brother of Moses' wife. He was a Midianite. Moses said to Hobab, ‘We are leaving here now to go to another place. The Lord has said to us, “I will give that place to you.” The Lord has promised to help Israel's people with good things. So come with us and we will take care of you.’

30But Hobab said to him, ‘I will not come. Instead, I will return to my own country and to my family there.’

31Moses said, ‘Please do not leave us. You know good places for us to put up our tents in the desert. So you can be our guide.

32And if you come with us, we will share with you the good things that the Lord gives to us.’

33So the Israelites left the Lord's mountain. They travelled for three days. During that time, the Levites carried the Lord's Covenant Box in front of them. That was so that the Lord could show them where to make their camp.
