1 Chronicles 3:1-4 lists the sons born to David in Hebron and Jerusalem, giving names to the 'more sons' from this verse.

Deuteronomy 17:17 forbids kings from multiplying wives—a command David violates here by taking more wives in Jerusalem.

2 Samuel 5:13 gives the parallel account: David took more concubines and wives in Jerusalem, confirming the same event.

1 Kings 11:3 shows Solomon also multiplied wives and it turned his heart away—extending the pattern and its consequence.
