Charles Ellicott Commentary 1 Chronicles 14:3

"And David took more wives at Jerusalem; and David begat more sons and daughters." — 1 Chronicles 14:3 (ASV)

And David took more wives. —The verse is considerably abbreviated as compared with Samuel, which reads, “concubines and wives from Jerusalem, after he had come from Hebron.” The concubines are not omitted because of offence, for they are mentioned in 1 Chronicles 3:9.
