26 `And we say, Pray let us prepare for ourselves to build the altar -- not for burnt-offering nor for sacrifice --

Joshua 22:26 Meaning and Commentary

Joshua 22:26

Therefore we said
One to another, in order to prevent the apostasy of our children from God, their departure from his worship, and going into idolatry:

let us now prepare to build us an altar;
get materials ready, and set about it instantly, without any delay, while the thing dwells upon our minds:

not for burnt offering, nor for sacrifice;
not for offerings of any kind required by the law, neither for sin offerings nor trespass offerings, nor any other not named.

Joshua 22:26 In-Context

24 `And if not, from fear of [this] thing we have done it, saying, Hereafter your sons do speak to ours sons, saying, What to you and to Jehovah God of Israel?
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.
