דברי הימים א, פרק י״ד, פסוק ג׳

The expansion of a royal family often serves as a clear sign of a growing and secure kingdom. As David established his rule in Jerusalem, his household grew significantly. He married additional wives, building upon the family he had already started during his earlier years in Hebron [ביאור שטיינזלץ]. This deliberate expansion was done with the specific goal of having many sons and daughters [מלבי״ם]. Ultimately, the growth of his family stands as a powerful testament to his overall strength and the firm establishment of his power [רש״י].

A comparison with the parallel historical account in the Book of Samuel reveals a subtle but meaningful difference. The earlier record notes that David took both wives and concubines, whereas the later narrative mentions only wives. This specific omission was a deliberate choice made to protect and maintain David's honor [חומת אנך].
