Ezekiel 44:9-11 Holman Christian Standard Bible (HCSB)
9 “This is what the Lord God says: No foreigner, uncircumcised in heart and flesh, may enter My sanctuary, not even a foreigner who is among the Israelites. 10 Surely the Levites who wandered away from Me when Israel went astray, and who strayed from Me after their idols, will bear the consequences of their sin. 11 Yet they will occupy My sanctuary, serving as guards at the temple gates and ministering at the temple. They will slaughter the burnt offerings and other sacrifices for the people and will stand before them to serve them.
