The Pope speaks on Isaiah 33:13-16:

The Canticle found in the 33^rd chapter of the Book of Isaiah announces God's condemnation of human injustice and his summons to a life of holiness in fidelity to the Covenant. According to the Prophet, only those who walk in the way of justice and integrity, rejecting all complicity with evil, will enter the Lord's holy Temple and dwell in his peace. God's peace is described as an abundance of bread and water. In this rich imagery, the Church sees a foreshadowing of the life-giving sacraments of Baptism and the Eucharist.
