'Part in the Lord' in the Bible

For the LORD hath made Jordan a boundary between us and you, ye children of Reuben and children of Gad; ye have no part in the LORD. So shall your children make our children cease from fearing the LORD.

But that it may be a witness between us, and you, and our generations after us, that we may do the service of the LORD before him with our burnt-offerings, and with our sacrifices, and with our peace-offerings; that your children may not say to our children in time to come, Ye have no part in the LORD.
