Joshua 22:11

(11) Have built an altar.—Rather, have built the altar. As appears by Joshua 22:28, it was a representation of the altar of Jehovah: a copy of the one altar which He had given to Israel for sacrifice. The design was to set up on the east of Jordan a likeness of that altar which was established on the west, that the tribes on the other side of Jordan might appeal to it as a proof that they also were the people of Jehovah.
