Numbers 10:30

27 And over the host of the tribe of the children of Naphtali was Ahira the son of Enan.

28 Thus were the journeyings of the children of Israel according to their hosts; and they set forward.

29 And Moses said unto Hobab, the son of Reuel the Midianite, Moses` father-in-law, We are journeying unto the place of which Jehovah said, I will give it you: come thou with us, and we will do thee good; for Jehovah hath spoken good concerning Israel.

30 And he said unto him, I will not go; but I will depart to mine own land, and to my kindred.

31 And he said, Leave us not, I pray thee; forasmuch as thou knowest how we are to encamp in the wilderness, and thou shalt be to us instead of eyes.

32 And it shall be, if thou go with us, yea, it shall be, that what good soever Jehovah shall do unto us, the same will we do unto thee.

33 And they set forward from the mount of Jehovah three days` journey; and the ark of the covenant of Jehovah went before them three days` journey, to seek out a resting-place for them.
