Joshua 22:21

19However, if the land of your possession is unclean, then pass over to the land of the possession of the LORD, in which the LORD’s tabernacle dwells, and take possession among us; but don’t rebel against the LORD, nor rebel against us, in building an altar other than the LORD our God’s altar.

20Didn’t Achan the son of Zerah commit a trespass in the devoted thing, and wrath fell on all the congregation of Israel? That man didn’t perish alone in his iniquity.’”

21Then the children of Reuben and the children of Gad and the half-tribe of Manasseh answered, and spoke to the heads of the thousands of Israel,

22“The Mighty One, God, the LORD, the Mighty One, God, the LORD, he knows; and Israel shall know: if it was in rebellion, or if in trespass against the LORD (don’t save us today),

23that we have built us an altar to turn away from following the LORD; or if to offer burnt offering or meal offering, or if to offer sacrifices of peace offerings, let the LORD himself require it.
