This family was more immediately interested in the decision of the point they came to question Moses upon; because it was this tribe which had at present no father, or elder of the house; and the inheritance was now in the person of Zelophehad's daughters. See Numbers 27:1.
Numbers 36:1-3
1 And the chief fathers of the families of the children of Gilead, the son of Machir, the son of Manasseh, of the families of the sons of Joseph, came near, and spake before Moses, and before the princes, the chief fathers of the children of Israel:
2 And they said, The LORD commanded my lord to give the land for an inheritance by lot to the children of Israel: and my lord was commanded by the LORD to give the inheritance of Zelophehad our brother unto his daughters.
3 And if they be married to any of the sons of the other tribes of the children of Israel, then shall their inheritance be taken from the inheritance of our fathers, and shall be put to the inheritance of the tribe whereunto they are received: so shall it be taken from the lot of our inheritance.
