A "Tekton" (builder/carpenter) in Nazareth. He was of the royal line of David, but lived in obscurity. He was a man of the working class, skilled with his hands, patient, and quiet.
He was betrothed to Mary. When she was found to be pregnant, he faced a crisis. The Law demanded he expose her or stone her. He decided to divorce her quietly. This reveals his character: he was "Just" but also "Kind."
He was formed by Integrity. Matthew 1:19 calls him a "righteous man." He cared about the Law, but he refused to use the Law to destroy a vulnerable person.
