Joshua 22:33-34

Young's Literal Translation

³³ and the thing is good in the eyes of the sons of Israel, and the sons of Israel bless God, and have not said to go up against them to war, to destroy the land which the sons of Reuben, and the sons of Gad, are dwelling in.

³⁴ And the sons of Reuben and the sons of Gad proclaim concerning the altar, that `it [is] a witness between us that Jehovah [is] God.'
