What does Joshua 22:28 mean?

Therefore said we, It shall be, when they so say to us or to our generations in time to come, that we shall say, Behold the pattern of the altar of Jehovah, which our fathers made, not for burnt-offering, nor for sacrifice; but it is a witness between us and you.

Therefore said we, that it shall be, when they should so say to us or to our generations in time to come, that we may say again, Behold the pattern of the altar of the Lord, which our fathers made, not for burnt offerings, nor for sacrifices; but it is a witness between us and you.

Therefore said we, It shall be, when they so say to us or to our generations in time to come, that we shall say, Behold the pattern of the altar of Jehovah, which our fathers made, not for burnt-offering, nor for sacrifice; but it is a witness between us and you.

For we said to ourselves, If they say this to us or to future generations, then we will say, See this copy of the Lord's altar which our fathers made, not for burned offerings or offerings of beasts, but for a witness between us and you.

`And we say, And it hath been, when they say <FI>so<Fi> 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 <FI>is<Fi> between us and you.

And if they will say so, they shall answer them: Behold the altar of the Lord, which our fathers made, not for holocausts, nor for sacrifice, but for a testimony between us and you.

And we said, If it shall be that in future they so say to us and to our generations, we will say, Behold the pattern of the altar of Jehovah which our fathers made, not for burnt-offering, nor for sacrifice, but as a witness between us and you.
