1 Chronicles 9:27-29

27They stayed at their places around God's house during each night. It was their work to keep it safe. Each morning they would use their key to open the gates.

28Some of the guards kept safe the valuable things that the priests used when they served the Lord. The guards counted those things when the priests brought them in. They counted them again when the priests took them out.

29Some other guards kept safe the tools and the valuable things that were in the Holy Place. Some guards took care of the flour, wine, olive oil, incense and spices.
