KJV:

10 And the Levites that are gone away far from me, when Israel went astray, which went astray away from me after their idols; they shall even bear their iniquity.
11 Yet they shall be ministers in my sanctuary, having charge at the gates of the house, and ministering to the house: they shall slay the burnt offering and the sacrifice for the people, and they shall stand before them to minister unto them.

NASB:

10 "But the Levites who went far from Me when Israel went astray, who went astray from Me after their idols, shall bear the punishment for their iniquity.
11 "Yet they shall be ministers in My sanctuary, having oversight at the gates of the house and ministering in the house; they shall slaughter the burnt offering and the sacrifice for the people, and they shall stand before them to minister to them.
