After the death of King David, and then with the help of Mother Bathsheba, Solomon ascended to the throne between the ages of 12 and 20. He ruled for approximately 40 years between 970 and 931 BC.

The Bible's First Book of Kings—widely believed to have been written centuries after the time period in question— says Solomon, king of Israel, built a defensive wall in Jerusalem.

Remember that King Solomon had 700 wives and 300 concubines, so he was “royally qualified” to write a love poetry Bible book. The three books follow one another together, and Proverbs is first.
