1 Chronicles 6:50-53 - Ellicott's Commentary On The Whole Bible

(50-53) If the chronicler, and not his source, be held responsible for this repetition of the Aaronite line, we may regard it as an instance of his inartificial method of making a new start. He is about to pass from the Levitical genealogies to their cities and domains, and he first partially recapitulates the line of Aaron’s sons, because their seats are to be described first. (Comp. 1 Chronicles 6:1-2 with 16, 18.) He stops at Ahimaaz, who lived in the age of David and Solomon, because, apparently, the preceding section was mainly concerned with the Levites of that epoch.
