That would be Solomon.
A display of this wisdom is seen in 1 Kings 3:16-28 where two women fight over a child (one of whom is the real mother). When Solomon decides to split the baby in half, both "mothers" reveal themselves, the one by her selfless love, the other (the fake) by her indifference.
Earlier, Solomon had asked God for wisdom to lead God's people, a request which pleased God. For this Solomon was granted both wisdom and riches.
Solomon is credited with writing many of the Proverbs as well as the Book of Ecclesiastes (another book of wisdom literature) as well as Song of Solomon.
