Who wrote the book of Proverbs? This book was written by multiple authors though Proverbs 1:1 attributes the book to King Solomon, David’s son. Why would that be? Solomon was seriously invested in learning wisdom. He studied intently and wrote many of the proverbs, and his example of prioritizing wisdom affected those in his kingdom. Though he didn’t write all of this book, Solomon can be considered the one who initiated and inspired the Israelites’ “wisdom literature.” (Source 1, 1 Kings 4:29-33)
