The breastplate prayer

I bind unto myself today
The power of God to hold and lead,
His eye to watch, His might to stay,
His ear to hearken to my need.
The wisdom of my God to teach,
His hand to guide, His shield to ward;
The word of God to give me speech,
His heavenly host to be my guard.

Christ, be with me, Christ before me, Christ behind me,
Christ in me, Christ beneath me, Christ above me,
Christ on my right, Christ on my left.
Christ when I lie, Christ when I sit, Christ when I arise.
Christ in the heart of everyone who thinks of me,
Christ in the mouth of everyone who speaks of me,
Christ in every eye that sees me,
Christ in every ear that hears me.
Salvation is of the Lord,
Salvation is of the Christ,
May your salvation, O Lord, be ever with us.

--St. Patrick
