The answer is: 19

1 Chr 3:1-9

When we delve into the family tree of King David, it's a vibrant tapestry that tells not just of a ruler but also of a father. The number 19 might sound impressive on its own, but consider that these sons came from different wives, reflecting the complex family structure of the time. It’s fascinating to know that each of these sons had unique stories, aspirations, and sometimes dramatic arcs of their own!

Among the most notable are Solomon, who succeeded David and built the stunning Temple in Jerusalem, Absalom, known for his rebellion and elaborate hair, and Adonijah, who attempted to claim the throne for himself. Their stories are rich with themes of power, love, betrayal, and redemption—classic narrative threads that still resonate today.

Many folks might not realize that David also had daughters, though their names aren't as frequently mentioned. A notable daughter was Tamar, whose life story showcases the darker aspects of family dynamics and justice, falling prey to tumultuous situations often fueled by her half-brother, Amnon's, flawed desires.

In addition to just counting sons, it's intriguing to explore how these individuals represented not just family lines but also the unfolding drama of Early Israel’s monarchy, which was greater than the sum of its royal parts. Their stories lead us to consider broader themes of legacies and the human experience as chronicled in the annals of scripture. Whether through triumphs or tragedies, David's house can be a mirror reflecting our own complex lives.
