No, the Book of Proverbs is not in the New Testament. It is actually part of the Old Testament in the Bible. The Book of Proverbs is attributed to King Solomon and is a collection of wise sayings and teachings aimed at providing guidance on how to live a righteous and moral life.
The New Testament, on the other hand, contains the teachings of Jesus Christ and the writings of his apostles. It includes books like the Gospels, Acts, the Epistles, and Revelation, which focus on the life and teachings of Jesus and the early Christian church.
While both the Old and New Testaments are important parts of Christian scripture, they serve different purposes and are rooted in different historical contexts. Proverbs is particularly known for its emphasis on wisdom and practical living, making it a valuable resource for moral guidance within the broader Biblical narrative.
