1 Chronicles 9:26

For these Levites, the four chief porters, were in their set office R.V. For the four chief porters, who were Levites, were in a set office. It seems from this passage (and also from the structure of this chapter; cp. 1 Chronicles 9:10; 1 Chronicles 14:17) that the doorkeepers were not, as a body, Levites. Their leaders however, being Levites, were placed in positions of greater trust; cp. 1 Chronicles 26:20-28. In 2 Chronicles 34:9 Levites appear exercising the duties of doorkeepers, but this does not prove that all doorkeepers were Levites.

chambers i.e. store-chambers in which tithes and sacred vessels were kept; cp. 2 Chronicles 31:5; 2 Chronicles 31:11-12; Nehemiah 13:4-9. The chambers were probably built as outbuildings round the Court of the Temple; cp. 1Ch 23:28; 1 Chronicles 28:12.
