Numbers 10:30

28Thus were the travels of the children of Israel according to their armies; and they went forward.

29Moses said to Hobab, the son of Reuel the Midianite, Moses’ father-in-law, “We are journeying to 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 spoken good concerning Israel.”

30He said to him, “I will not go; but I will depart to my own land, and to my relatives.”

31Moses said, “Don’t leave us, please; because you know how we are to encamp in the wilderness, and you can be our eyes.

32It shall be, if you go with us—yes, it shall be—that whatever good the LORD does to us, we will do the same to you.”
