Joshua 22:27

27 but a witness it [is] between us and you, and between our generations after us, to do the service of Jehovah before Him with our burnt-offerings, and with our sacrifices, and with our peace-offerings, and your sons do not say hereafter to our sons, Ye have no portion in Jehovah.

Joshua 22:27 In-Context

25 for a border hath Jehovah put between us and you, O sons of Reuben, and sons of Gad -- Jordan; ye have no portion in Jehovah -- and your sons have caused our sons to cease, not to fear Jehovah.
26 `And we say, Pray let us prepare for ourselves to build the altar -- not for burnt-offering nor for sacrifice --
27 but a witness it [is] between us and you, and between our generations after us, to do the service of Jehovah before Him with our burnt-offerings, and with our sacrifices, and with our peace-offerings, and your sons do not say hereafter to our sons, Ye have no portion in Jehovah.
28 `And we say, And it hath been, when they say [so] unto us, and unto our generations hereafter, that we have said, See the pattern of the altar of Jehovah, which our fathers made -- not for burnt-offering nor for sacrifice -- but a witness it [is] between us and you.
29 `Far be it from us to rebel against Jehovah, and to turn back to-day from after Jehovah, to build an altar for burnt-offering, for present, and for sacrifice, apart from the altar of Jehovah our God, which [is] before His tabernacle.'
