40 It was a memorial for the Israelites, that no outsider who is not a descendant of Aaron should approach to burn incense before the Lord, that he might not become like Korah and his company—just as the Lord had spoken by the authority of Moses.

Darby

40 as a memorial to the children of Israel, that no stranger who is not of the seed of Aaron come near to burn incense before Jehovah, that he be not as Korah, and as his band, as Jehovah had said to him through Moses.

KJV

40 [To be] a memorial unto the children of Israel, that no stranger, which [is] not of the seed of Aaron, come near to offer incense before the LORD; that he be not as Korah, and as his company: as the LORD said to him by the hand of Moses.
