These dwelt in Jerusalem - Jerusalem was partly within the limits of the tribe of Benjamin Joshua 18:28; but we do not hear of Benjamites inhabiting it until after the return from the captivity 1-Chronicles 9:3; Nehemiah 11:4.

These were heads of the fathers - On the following verses Dr. Kennicott has labored hard to restore the true reading. See his detailed comparison of these and their parallel passages in his Hebrew Bible, vol. ii., p. 667.

These [were] heads of the (e) fathers, by their generations, chief [men]. These dwelt in Jerusalem.
(e) The chief of the tribe of Benjamin, who dwelt in Jerusalem.

These were heads of the fathers, by their generations, chief men,.... All from 1-Chronicles 8:14, the sons of Elpaal and their sons:
these dwelt in Jerusalem; part of which always belonged to the tribe of Benjamin, see Joshua 15:63.

These dwelt in Jerusalem--The ordinary and stated inhabitants of Jerusalem were Judahites, Benjamites, and Levites. But at the time referred to here, the chiefs or heads of the principal families who are enumerated (1-Chronicles 8:14-27) established themselves in the city after their return from the captivity.

Heads of the fathers, &c. - Particular notice is taken of these, that others, at their return from captivity, might be induced to settle there too, which it seems few were willing to do, because it was the post of danger. Many great and mighty nations were then upon earth, and many illustrious men in them, whose names are buried in perpetual oblivion, while the names of multitudes of the Israel of God, are here carefully preserved in everlasting remembrance: a figure of God's writing the names of his spiritual Israel, in the Lamb's book of life.
