NET

19 But if your own land is impure, cross over to the Lord’s own land, where the Lord himself lives, and settle down among us. But don’t rebel against the Lord or us by building for yourselves an altar other than the altar of the Lord our God.

Darby

19 Notwithstanding, if the land of your possession is unclean, come over into the land of the possession of Jehovah, where Jehovah's tabernacle dwelleth, and take possession amongst us; but rebel not against Jehovah, and rebel not against us, in building for yourselves an altar besides the altar of Jehovah our God.

KJV

19 Notwithstanding, if the land of your possession [be] unclean, [then] pass ye over unto the land of the possession of the LORD, wherein the LORD'S tabernacle dwelleth, and take possession among us: but rebel not against the LORD, nor rebel against us, in building you an altar beside the altar of the LORD our God.
