This past weekend Pope Francis visited a parish in Rome and at the end of Mass the First Communion children came forward, gathered around the altar, and with the accompaniment of a guitar sang a blessing on the pope who kept his head bowed through the whole piece.
Here's a translation of what they sang:
May the Lord bless you and keep you.
May He show His face to you and have mercy.
May He turn His countenance to you and give you peace.
May the Lord bless you.
