Adam Clarke on 1 Chronicles 9:41

And Ahaz - This is added by our translators from 1Chr 8:35, but such liberties should only be taken in a note; for although the words are now sufficiently distinguished from the text by being printed in Italics, yet it is too much to expect that every editor of a Bible will attend to such distinctions, and in process of time the words will be found incorporated with the text. 1Chr 9:35, and the following verses, are a repetition of what we find in 1Chr 8:29-38 (note), where see the notes.
