Today I gird myself
With the strength of God to direct me,
The might of God to exalt me,
The mind of God to lead me,
The eye of God to watch over me,
The ear of God to hear me,
The word of God to speak to me,
The hand of God to defend me,
The path of God to go before me,
The shield of God to guard me,
The help of God to protect me
Against the snares of demons,
Against the temptation of vices,
Against the tendencies of nature,
Against everyone who will wish me ill,
Far and near,
Among few and among many.
