Numbers 10:28-30

²⁸This was the order of the camps, and marches of the children of Israel by their troops, when they set forward.

²⁹And Moses said to Hobab the son of Raguel the Madianite, his kinsman: We are going towards the place which the Lord will give us: come with us, that we may do thee good: for the Lord hath promised good things to Israel.

³⁰But he answered him: I will not go with thee, but I will return to my country, wherein I was born.
