The four chief porters who were over all the two hundred and twelve, and had one over them, Ch1 9:17, these were never changed, nor went into the country villages; but were always upon the spot, and in their office, superintending the rest: and were over the chambers and treasuries of the house of God; see Ch1 26:20.

A repetition of the genealogy of king Saul (Ch1 9:35-44).
