Saint Joseph, also referred to as Joseph the Betrothed and as Joseph of Nazareth, was the foster-father of Jesus, according to the New Testament (Matthew 1:16; Luke 3:23). Not much is known of Joseph's life on Earth, except that he was "of the House of David" and lived in the town of Nazareth. His date of death is unknown, though he was still living when Jesus was twelve years old.
Hail Joseph the just, Wisdom is with you; blessed are you among all men and blessed is Jesus, the fruit of Mary, your faithful spouse. Holy Joseph, worthy foster-father of Jesus Christ, pray for us sinners and obtain divine Wisdom for us from God, now and at the hour of our death. Amen. -St. Louis Marie de Montfort
