Rather, let it be a witness between us and you and the generations to come, that we will worship the LORD in His presence with our burnt offerings, sacrifices, and peace offerings.’ Then in the future, your descendants cannot say to ours, ‘You have no share in the LORD!’
KJV
But [that] it [may be] a witness between us, and you, and our generations after us, that we might 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.
ASV
but it shall be a witness between us and you, and between our generations after us, that we may do the service of Jehovah 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 portion in Jehovah.
