Scholars note that this list of Levitical cities is very similar to the one in Joshua 21, but with some differences. For example, 'Hilen' here is called 'Holon' in Joshua. Commentators explain that these variations, along with some apparent omissions in the surrounding verses, are likely due to scribal updates or copying errors over centuries. This shows the human element in transmitting the text, while affirming that the core message of God's provision for the Levites remains clear.
