Numbers 10:29-30

Now Moses said to Hobab the son of Reuel the Midianite, Moses’ father-in-law, “We are setting out for the place of which the LORD said, ‘I will give it to you.’ Come with us, and we will treat you well; for the LORD has promised good things to Israel.” And he said to him, “I will not go, but I will depart to my own land and to my relatives.”
